Introduction

Let's be honest—titanium has a reputation. It's that exotic metal they use in fighter jets and Mars rovers. The stuff that costs a fortune and requires special handling. And yes, all of that is true. But here's what most people don't realize: titanium is also one of the most versatile materials for custom parts manufacturing.

I've spent years in this industry, and I still get surprised by what customers ask us to make. Titanium jewelry? Absolutely. Titanium bicycle frames? All day long. Titanium submarine parts? Yep, done that too.

The real question isn't "can it be made from titanium?"—it's "should it be made from titanium?" If your application needs light weight, corrosion resistance, high strength, or biocompatibility, the answer is probably yes.

This guide walks through exactly what's possible with custom titanium parts, based on real projects we've handled and the current capabilities of modern manufacturing.

First Things First: Choosing Your Titanium Grade

Before we dive into what you can make, you need to understand what you're making it from. Titanium isn't one material—it's a whole family.

The Pure Titanium Grades (1-4)

Think of these as the "everyday" titanium. They're not the strongest, but they're incredibly corrosion-resistant and easy to work with.

Grade 1 is the softest and most formable. We use it for things that need serious bending—chemical processing equipment, marine components, parts that get formed into complex shapes. It's like the aluminum foil of titanium, if aluminum foil were incredibly expensive and corrosion-proof.

Grade 2 is the workhorse. About 70% of commercially pure titanium parts we make are Grade 2. It's got that sweet spot of strength and workability. Architectural cladding, medical devices, industrial components—Grade 2 handles it all.

Grade 3 steps up the strength game. Less common, but we spec it when applications need more muscle but still want that pure titanium corrosion resistance.

Grade 4 is the strongest of the pure grades. You'll find it in surgical instruments and dental implants where strength matters but you can't use alloys.

The Alloy Grades (The Heavy Hitters)

Ti-6Al-4V (Grade 5) is the rockstar. About 50% of all titanium used globally is this alloy . It's got aluminum for strength and vanadium for stability, delivering around 895 MPa tensile strength while staying relatively light. Aerospace structural parts, engine components, high-end automotive, medical implants—Grade 5 does it all.

Ti-6Al-4V ELI (Grade 23) is Grade 5's more refined cousin. "ELI" means Extra Low Interstitials—basically, they've removed trace elements that can cause brittleness. Result? Better fracture toughness and ductility. This is the gold standard for medical implants and cryogenic applications.

Then there's the specialty alloys—Grade 7 with palladium for extreme corrosion resistance, Grade 9 (Ti-3Al-2.5V) for hydraulic tubing, and various beta alloys for springs and fasteners. Each exists because someone needed something specific that standard grades couldn't deliver.

How We Actually Make Custom Titanium Parts

The grade matters, but the process determines what's possible. Here's the reality of each manufacturing method.

CNC Machining: When Precision Is Everything

If your part needs tight tolerances—and I mean tight, like ±0.005mm—CNC machining is your answer.

Modern 5-axis machining centers can create geometries that would have seemed impossible twenty years ago. We're talking complex housings with internal passages, threaded features, undercuts, the works. The only real limitation is tool access. If a cutter can reach it, we can machine it.

Real-world parts we've machined:

• Aerospace brackets with tolerance stacking requirements that kept engineers up at night

• Valve bodies for chemical processing with internal sealing surfaces

• Medical instrument handles that need to feel perfect in a surgeon's hand

• Custom fasteners with non-standard threads and head styles

Maximum part size depends on your machine. Our largest CNC can handle 4000×1500×600mm. Minimum feature size? We've drilled holes down to 0.05mm, though your inspection department will hate you for it.

3D Printing / Additive Manufacturing: Complexity for Free

Here's where things get interesting. With 3D printing, complexity doesn't cost extra. Those lattice structures you see in concept renders? They're real now. Internal channels that would require multiple machined components? Printed as one piece.

The trade-off is surface finish and tolerance. As-built parts typically need some post-machining on critical surfaces. But for prototypes, one-offs, or geometries that simply can't be machined, it's transformative.

The coolest applications we've seen:

• Patient-specific hip implants generated from CT scan data

• Aerospace brackets with organic shapes optimized by AI for minimum weight

• Custom surgical guides for single-use applications

• Heat exchangers with internal channels that maximize surface area

Current technology maxes out around 245×245×330mm for most machines. Wall thickness down to 0.25mm is possible if you're careful with design.

Forging: When Strength Is Non-Negotiable

If your part needs to handle serious loads, forging is the answer. The process aligns the grain structure with the part geometry, creating components that simply outperform machined equivalents.

What we forge regularly:

• Engine disks that spin at thousands of RPM while red-hot

• Landing gear components that absorb impact forces

• Structural fittings where failure means the aircraft doesn't stay airborne

• Seamless rings up to 650mm diameter for pressure vessels

The catch? Tooling costs mean forging only makes sense for production runs, not one-offs.

Casting: Complex Shapes in Medium Volumes

Investment casting (lost wax) lets us create parts with internal cavities and complex external geometry that would be expensive to machine. Think impellers, valve bodies, pump housings.

Capability range:

• Part weights from 5 grams to 300kg

• Minimum wall thickness down to 0.4mm for die casting

• Tolerances around ±0.02mm to ±0.5mm depending on features

Casting doesn't achieve the same mechanical properties as forging, but for many applications, it's more than adequate.

Sheet Metal Fabrication: Thin Walls, Light Weight

When your part needs to be thin, light, and possibly hollow, sheet metal fabrication is the answer. Laser cutting, bending, punching, rolling—these techniques turn flat stock into three-dimensional enclosures, ducts, and brackets.

Typical parts:

• Electronic enclosures for marine environments

• Heat shields for automotive exhaust

• Panels for aircraft interiors

• Medical device housings

Material thickness ranges from 0.5mm to about 4.75mm. Beyond that, you're in plate territory and different rules apply.

Extrusion: Long Parts with Consistent Cross-Sections

Need a long piece with a complex profile that stays the same from end to end? Extrusion is your process. Titanium gets pushed through a die under enormous pressure, emerging as a continuous length that gets cut to size.

What extrusion handles well:

• Structural beams and angles

• Channels and T-sections

• Complex profiles with multiple cavities

• Tubing with internal features

Wall thickness control down to ±0.05mm is achievable. Straightness better than 1/1000. Surface finish can hit Ra0.8μm.

Welding and Assembly: Making Big Things from Small Things

Eventually, parts need to join together. Titanium welding requires absolute purity—oxygen contamination turns welds brittle. That means argon shielding, clean room conditions, and skilled welders who understand the material.

Assembly techniques we use:

• TIG welding for most applications

• Robotic welding for consistent production

• Mechanical fastening with titanium fasteners

• Adhesive bonding for certain applications

The key insight? Titanium doesn't like to be hot. It reacts with oxygen, nitrogen, and hydrogen at elevated temperatures. Proper shielding isn't optional—it's survival.

Surface Finishing: The Last 10% That Makes 90% of the Difference

Raw titanium has a certain industrial charm, but finishing transforms parts into finished products.

The right finish can turn a functional part into a beautiful one, or extend service life by years.

So What Can You Actually Make? Let's Get Specific

Fasteners and Small Components

Bolts, screws, nuts, washers, studs—all of these are routine. The key is understanding that titanium fasteners behave differently than steel. They gall (seize) more easily, so anti-seize compounds or specialized thread forms are often necessary.

Real-world example: We made a run of custom shoulder bolts for a racing team's suspension system. Weight savings: about 40% over the steel originals. Cost: significant. Value to the team: priceless, because those ounces mattered on the track.

Shafts and Rods

Drive shafts, piston rods, actuator shafts—any application where you need stiffness without weight. The high specific strength of titanium means you can often reduce diameter compared to steel, saving even more weight.

Tolerance capability: We regularly hold ±0.005mm on critical diameters with grinding. Straightness can be held to within 0.025mm over 300mm if needed.

Flanges and Fittings

Weld neck flanges, slip-ons, blinds, socket welds—all the standard pipe fittings, but in titanium. The challenge is matching the pressure ratings and dimensions of steel counterparts while accounting for titanium's different mechanical properties.

Common grades: Grade 2 for corrosion service, Grade 5 for high-pressure applications. We've supplied flanges for chemical plants, offshore platforms, and even a nuclear research facility.

Valves and Pumps

Bodies, bonnets, balls, seats, stems, impellers—complete valve and pump assemblies in titanium. The corrosion resistance makes these ideal for seawater, chemical processing, and pharmaceutical applications where contamination can't happen.

One interesting project: A custom butterfly valve for a desalination plant. The standard catalog item would have worked, but the plant layout required specific flange orientations and a shorter face-to-face dimension. Custom titanium fabrication solved it.

Heat Exchangers

Tubes, tube sheets, baffles, shells—titanium heat exchangers are common in marine and chemical applications because nothing else handles salt water like titanium.

Grade selection: Grade 1 or 2 for most tubing (better formability), Grade 7 for aggressive chemistries, Grade 9 for higher pressure requirements.

Pressure Vessels

Tanks, reactors, autoclaves—custom pressure vessels in titanium handle corrosive contents at elevated pressures and temperatures. Design follows ASME Section VIII, with material specified per ASME SB-265.

Size range: From lab-scale reactors a few liters in volume to production vessels holding thousands of gallons.

Structural Profiles

Angles, I-beams, channels, T-sections, Z-sections—when standard catalog sizes don't fit your design, custom extrusion delivers exactly what you need.

Application examples:

• Aircraft floor supports with specific flange widths

• Architectural mullions with custom weather seals

• Shipbuilding stiffeners with optimized section properties

Aerospace Components

This is where titanium truly shines. Compressor blades, disks, casings, vanes—engine parts that see high temperatures and stresses. Fuselage frames, wing attachments, bulkheads—structural parts where weight savings multiply throughout the aircraft.

The numbers: A pound saved in the airframe saves additional pounds in fuel, engines, and landing gear. It's why aerospace will pay premium prices for titanium parts.

Medical Implants

Hip stems, knee components, spinal rods, bone plates, dental implants—titanium's biocompatibility means the body accepts it without rejection. Grade 23 ELI is the standard, with surface treatments that encourage bone growth.

Custom trends: Patient-specific implants generated from CT/MRI data. Surgeons can now order implants matched exactly to a patient's anatomy, improving outcomes and reducing surgery time.

Automotive and Racing

Exhaust systems, connecting rods, valves, suspension components, fasteners—racing teams have used titanium for decades. Now it's trickling down to high-end street cars.

Why it matters: Reciprocating weight is the enemy. A lighter connecting rod means the engine can rev faster, respond quicker, and make more power. Unsprung weight in suspension improves handling. Every pound saved in rotating or reciprocating mass multiplies in effect.

Marine and Offshore

Subsea connectors, propeller shafts, hull fittings, desalination components—the ocean is brutal on metals. Titanium laughs at salt water.

Depth rating: We've supplied components certified for 3000m water depth. The pressure is enormous, but titanium handles it.

Consumer Products

Eyewear frames, watches, jewelry, smartphone cases, pens—titanium's weight, feel, and hypoallergenic properties make it premium consumer goods.

Finishing matters here: Anodizing creates colors without dyes (the color comes from the oxide layer thickness), polishing creates mirror finishes, bead blasting gives a technical matte look.

Architectural Elements

Cladding panels, roofing, railings, door frames, sculptures—titanium in architecture is permanent. It doesn't rust, doesn't stain, doesn't need painting. The oxide layer is self-healing.

Notable installations: The Guggenheim Museum Bilbao uses titanium cladding. It's been there since 1997, still looks new.

Electrical and Electronic

Sputtering targets, electrodes, heat sinks, instrument housings—titanium's properties serve unexpected niches.

Sputtering targets: Ultra-high purity titanium for semiconductor manufacturing. The material must be perfect—no inclusions, no contamination, exact composition.

Heat sinks: Titanium's thermal conductivity is lower than aluminum or copper, but its corrosion resistance makes it the choice for harsh environments where other materials would fail.

The Design Freedom: What Each Process Enables

Here's the practical reality of what each manufacturing method can achieve:

Minimum feature sizes worth knowing:

• Machined holes: Φ0.05mm (good luck measuring it)

• Die cast walls: 0.4mm

• Sheet metal: 0.5mm

• 3D printed features: 0.25mm

• Threads: M1.5 (smaller exists, but why?)

The Standards You Need to Know

When ordering custom titanium parts, referencing standards keeps everyone on the same page.

Pro tip: If your part goes into a safety-critical application, specify the standard AND require certification. Paperwork matters when things go wrong.

How Custom Parts Actually Get Made

The journey from idea to part follows a predictable path:

1. Design and Specification
You know what the part needs to do. We help translate that into material grade, manufacturing process, and tolerances. The 3D CAD model gets refined for manufacturability.

2. Process Selection
One part, many ways to make it. We choose based on quantity, geometry, and requirements. Sometimes hybrid approaches make sense—cast near-net shape plus machining for critical features.

3. Prototyping
For anything complex or critical, prototype first. CNC machining or 3D printing gets you a physical part to verify fit and function before committing to production tooling.

4. Production
Tooling fabrication (if needed). Material procurement with certs. Manufacturing with in-process inspection. Heat treatment if required.

5. Quality Assurance
CMM inspection for critical dimensions. NDT as specified (ultrasonic, X-ray, dye penetrant). Mechanical testing for certifiable properties. Surface finish verification.

6. Finishing and Packaging
Surface treatment. Cleaning and passivation. Protective packaging. Shipping documentation.

What's Coming Next in Titanium Custom Parts

Additive Manufacturing Keeps Growing

The technology improves every year. Bigger build volumes, faster speeds, better surface finish. We're not at the point of printing entire aircraft wings, but the trajectory is clear.

Sustainable Manufacturing

Titanium's dirty secret: making it from ore is energy-intensive. But recycling titanium scrap is much more efficient. New processes like FAST-Forge can take machining waste (swarf) and turn it directly into forging preforms. Less waste, lower cost, smaller environmental footprint.

Hybrid Manufacturing

Combine additive and subtractive in one workflow. Print near-net shape, then machine critical surfaces. Design freedom plus precision tolerances.

Digital Integration

AI helping with design optimization. Digital twins simulating manufacturing. Real-time process monitoring catching issues before they become scrap.

New Alloys

Metallurgists keep developing better titanium alloys. Higher temperature capability. Better formability. Lower cost. Each new alloy expands what's possible in custom parts.

The Bottom Line

So what titanium custom parts can you actually make?

Anything that makes sense for the material.

If your application needs:

• Light weight with high strength

• Corrosion resistance in harsh environments

• Biocompatibility for medical use

• High-temperature capability

• A premium look and feel

...then titanium deserves consideration.

The manufacturing methods exist. The expertise is available. The only real question is whether the value titanium provides justifies its cost.

For aerospace, medical, marine, chemical processing, high-end automotive, and premium consumer goods, the answer is increasingly yes.

And if you can imagine it, we can probably make it.
