The Top Chinese OEM/ODM solutions Partner
We Offer a Variety of Materials for Custom Parts
Material selection determines whether a part works, lasts, can be made cost-effectively, and meets all functional and regulatory demands. Skipping this step leads to redesigns, production delays, or field failures.
Check out our wide selection of quality materials, those materials meeting the needs of different projects for strength, corrosion resistance, and specialized physical properties for customized parts by CNC machining, injection molding, sheet metal fabrication and 3D printing, vacuum casting, die casting for both prototyping and production stages.

FAQs About Materials
What are the most commonly used metal materials in CNC machining?
Widely‑used metals include aluminum 6061‑T6, 7075‑T6, stainless steel 304/316, carbon steel, brass C36000 and titanium Ti‑6Al‑4V. Typical engineering plastics cover POM(Delrin), Nylon, PC, ABS, PEEK and PTFE. Final selection depends on strength, weight, corrosion resistance, temperature, tolerance and budget requirements.

What are the most common materials for stamping parts?
- SPCC cold‑rolled steel sheet: General‑purpose for enclosures and brackets, requires surface treatment for corrosion resistance.
- 6061‑O aluminum sheet: Lightweight, good for chassis and heat‑dissipation shells.
What are the most common materials as tool Steels?
- P20 (1.2311): Pre‑hardened steel for injection‑mold and vacuum‑casting tools for medium‑low volume runs.
- H13 (1.2344 / 1.2344): Heat‑resistant for die‑casting molds and high‑cycle injection molds.
Which metal materials are suitable for die casting?
The common used materials for die casting are aluminum alloys, zinc alloys, and magnesium alloys. The most commonly are:
- ADC12 aluminum: Most popular die‑cast alloy, excellent fluidity for thin‑wall complex housings.
- Zamak‑5 zinc alloy: High detail reproduction for small decorative precision parts.
What is the best general‑purpose CNC machining material?
Aluminum 6061‑T6 is most versatile option. It machines fast, balances strength‑to‑weight ratio, supports anodizing and various surface finishes, and keeps costs under control for prototypes and mass‑production structural components, housings and fixtures.
What are common materials for vacuum casting parts?
Vacuum casting uses liquid PU (polyurethane) series as main casting materials, simulating properties of plastics, rubber and even some hard‑rigid parts. They are ABS like, PP like, silicone like materials.
