We turn and mill titanium auto parts for engine, suspension and drivetrain use. Ti-6Al-4V and CP grades, held to ±0.005 mm, finished with anodizing or bead blasting. One prototype or a 10,000-part run.
These are the four failures we hear about most often from automotive teams moving a part from aluminum to titanium.
Titanium conducts heat poorly. Run aluminum feeds and speeds and the cutting edge reaches 1,000 °C while the chip stays cool. Tools fail mid-run, and you lose the finishing passes on a batch that was already 80 percent complete.
Suspension arms, brackets and turbo flanges are often 1.5–2 mm thick. Heavy vise pressure distorts the part, the cut measures on size in the machine, and the part relaxes oval once the jaws open. Scrap rate climbs and nobody sees it until final inspection.
You send drawings to three shops. Two go quiet for a week because they have never cut a titanium thin wall, and the tooling cost they eventually quote is padded to cover their uncertainty. Your program slips while you wait.
Titanium galls against tooling and against mating steel parts. A turned O-ring groove or flange face picks up smeared metal, and the surface that was supposed to seal at pressure leaks during the bench test.
Three things decide whether a titanium part comes off the machine in tolerance: tooling, heat control and how the part is held.
Ti-6Al-4V work-hardens fast. We cut it with sharp, uncoated carbide or AlTiN-coated inserts at low surface speed and high feed per tooth, so the heat leaves with the chip instead of soaking into the part. Through-spindle high-pressure coolant reaches the cutting edge on deep bores and long turning passes.
On a mill-turn center the part stays in one setup from bar to finished profile. Fewer setups means fewer chances to lose concentricity between a bearing journal and its bore.
Thin-wall titanium moves under clamp load. We build soft jaws, expanding mandrels or dedicated fixtures that spread the load over a large area, and we rough, stress-relieve and finish in separate passes so the part settles before the final cut.
Every job is measured on the CMM against the drawing, not against a first article that drifted. Raw material certificates come in before the bar is cut, in-process checks run on critical diameters, and the final report is available on request.
Grade choice drives cost, weight and wear life. This is how we usually see it split.
| Grade | Typical auto parts | Why this grade |
|---|---|---|
| Ti-6Al-4V (TC4) | Connecting rods, suspension arms, hub carriers | Highest strength of the common grades; heat treatable |
| Commercially pure Ti (TA1/TA2) | Exhaust shields, brackets, heat shields | Good corrosion resistance, easier to form and weld |
| Ti-6Al-4V ELI | Brake caliper pistons, valve components | Better toughness at low temperature |
| Titanium + hardcoat anodize | Wear pads, sliding contact faces | Hard oxide layer resists galling and abrasion |
Most titanium auto parts need more than one operation. All of it runs under one roof in Dongguan, with a second plant in Singapore.
16 simultaneous 5-axis centers cut complex suspension and engine geometry in fewer setups, which protects positional tolerance between features.
16 mill-turn centers handle shafts, pistons, bushings and fittings, turning and milling in a single cycle.
One-off titanium prototypes for fit checks and bench testing before you commit to tooling.
Anodizing, bead blasting, polishing, laser marking and plating, applied in house to titanium and its mating parts.
Brackets, heat shields and covers cut and formed from titanium sheet, then finished to match the machined parts.
CMM measurement, material certificates and dimensional reports supplied with the shipment on request.

Fifteen years in Dongguan, 150 technicians, and an automotive quality system in place since before titanium became a common request.
Three wholly-owned plants and 7,600 m² of manufacturing space in Dongguan, plus a plant in Singapore.
Held on critical diameters and bores, with CMM verification before the parts ship.
Also ISO 9001:2015, ISO 13485:2016 and ISO 27001:2022. Automotive traceability is standard, not an add-on.
Drawings go to an engineer, not a queue. You get a quotation and free DFM feedback within 12 hours.
Once the drawing and material are confirmed, machining can begin within 24 hours.
From a single prototype to a 10,000+ part run, on the same equipment and the same inspection routine.
Engine and drivetrain parts need tight concentricity and verified material traceability.
Low-volume titanium suspension and brake hardware, quoted fast and cut in small runs.
Wear-resistant titanium components for high-load tooling and automation fixtures.
Lightweight titanium parts for battery housings, busbars and thermal hardware.
Ti-6Al-4V (TC4) is the usual answer for load-bearing suspension and drivetrain parts. It heat treats to high strength and is stocked in bar and plate.
If the part sees mostly heat and corrosion rather than load, commercially pure TA2 costs less and machines more easily. Send the drawing and we will say which grade fits.
Yes, but the wall thickness and the length-to-diameter ratio decide how hard it is. Parts with walls under 1.5 mm need low-stress workholding and a rough-relieve-finish sequence.
We review the drawing before quoting and tell you if a feature will move after clamping. That conversation happens inside the 12-hour quote window.
Titanium is roughly 60 percent heavier than aluminum but about twice as strong, so a titanium part can be thinner and still carry the same load.
Machining cost is higher. Cuts run slower, tools wear faster, and the material costs several times more per kilogram. Use titanium where strength, heat or corrosion is the limiting factor.
We anodize in clear, colored and hardcoat, plus bead blasting, polishing, black oxide, powder coating and laser marking.
Laser marking has a minimum character height of 1.5 mm. For titanium, hardcoat anodizing is the common choice for sliding or wear contact faces.
There is none. We machine from one prototype to 10,000+ part runs on the same equipment.
Prototypes are a normal way to start. Many projects prove the design on one titanium part before releasing a production batch.
Quotation and free DFM analysis come back within 12 hours. Production can start within 24 hours of drawing and material confirmation, and parts ship in 3–5 days.
Our historical late-delivery probability is below 2 percent. Exact timing depends on the alloy and whether material is in stock.
Uploads are secure and confidential. We sign an NDA on request before drawings are shared.
Files stay inside the project team. We do not use customer parts or drawings in marketing material without written permission.
A 3D file or 2D drawing with tolerances, the alloy, the quantity and the finish you want. Tell us if any surface is a sealing or bearing face.
If the drawing is incomplete we will flag what is missing rather than guess. The DFM note comes back with the quote.
Upload a STEP file or PDF drawing. An engineer reviews it, flags DFM issues and returns a price. No minimum order quantity, no obligation.
