Custom precision CNC machining titanium alloy TC4 parts in China
High-accuracy titanium components machined from TC4 (Ti-6Al-4V) bar, plate and forging stock. From prototype batches to series production, we deliver tight-tolerance custom CNC machining TC4 titanium alloy parts in China for aerospace, medical, motorsport, robotics and industrial customers worldwide.
Precision TC4 titanium machining, from drawing to finished part
TC4 is the most widely used alpha-beta titanium alloy, combining high specific strength, excellent corrosion resistance and good thermal stability. Our machining facility in China specialises in converting this difficult-to-cut material into dimensionally stable, repeatable components with fine surface quality.
We produce custom CNC machining TC4 titanium alloy parts in China using 3-axis, 4-axis and simultaneous 5-axis machining centres, CNC lathes with live tooling, Swiss-type screw machines and wire / sinker EDM cells. Every programme is generated from your 3D model or 2D drawing, and first-article dimensions are verified before the batch is released.
Typical parts include structural brackets, hydraulic housings, valve bodies, fasteners, shafts, gears, drone frames, robot joint components and medical instrument parts. We machine from solid bar, forged blanks and plate, and we support secondary operations such as thread rolling, passivation, anodising, bead blasting and precision grinding in cooperation with qualified local suppliers.
Whether you need five prototype pieces or five thousand production units, the same engineering team, tooling strategy and inspection discipline apply. Our goal is to become your long-term partner for custom CNC machining TC4 titanium alloy parts in China.
TC4 (Ti-6Al-4V) material properties at a glance
The figures below refer to annealed TC4 bar and are typical values used for machining and design reference. Actual properties depend on product form, heat-treatment condition and inspection standard.
TC4 equivalent grades under international standards
TC4 is the Chinese designation for the classic Ti-6Al-4V alpha-beta titanium alloy. Around the world it is known by different commercial and standard names. The chemical composition and mechanical properties are essentially equivalent, although inspection clauses and product forms differ by standard.
| Region / Standard body | Designation | Typical specification | Common product form |
|---|---|---|---|
| China (GB/T) | TC4 | GB/T 3620.1, GB/T 2965 | Bar, plate, forging, wire |
| USA (ASTM) | Grade 5 / UNS R56400 | ASTM B348, B265, B381 | Bar, sheet, forging |
| USA (AMS) | Ti-6Al-4V | AMS 4911, 4928, 4965, 4979 | Sheet, bar, forging, wire |
| Russia (GOST) | VT6 (ВТ6) | GOST 19807, GOST 23755 | Bar, plate, forging, pipe |
| Germany (DIN / W-Nr) | 3.7164 / TiAl6V4 | DIN 17851, 17852, 17853 | Bar, plate, sheet, forging |
| International (ISO) | Ti-6Al-4V | ISO 5832-3, ISO 23210 | Medical bar, industrial bar |
| Japan (JIS) | Class 60 (60种) | JIS H4600, H4630, H4650 | Bar, plate, pipe, forging |
| Europe (BS / AFNOR) | TA6V | BS 2TA10, AIR 9174, NF L14-501 | Aerospace bar, forging, sheet |
Note: ELI (extra-low interstitial) variants such as TC4 ELI / Grade 23 are a separate grade with tighter oxygen, nitrogen and iron limits, typically used for surgical implants. The table above covers standard TC4 / Ti-6Al-4V only.
Machining processes we apply to TC4 titanium
Titanium is a poor heat conductor and chemically reactive at cutting temperature, so tool selection, spindle load, coolant strategy and chip evacuation are planned before a single tool touches the part. Our processes are tuned for TC4 and for consistent tool life.
Industries and applications we serve
The combination of high strength, low weight and corrosion resistance makes TC4 the material of choice across demanding industries. We regularly manufacture custom CNC machining TC4 titanium alloy parts in China for the following applications.
TC4 titanium parts we manufacture
A selection of custom CNC machining TC4 titanium alloy parts in China produced for customers across different industries. Every part is machined to customer drawing and inspected to the specified tolerance.
Inspection and dimensional control
Titanium parts are often used in safety-critical assemblies, so every dimension that matters is verified. We combine in-process checks with final inspection and keep records available for every batch.
Why customers choose us for TC4 titanium parts
We focus on titanium and difficult-to-cut alloys rather than treating them as a side business. This specialisation shows in tool life, surface finish, dimensional repeatability and on-time delivery.
