What Types of Raw Materials CNC Machining Use?

More than 28 different grades of metal and special alloy materials are available at HZW.

Metal and Alloy: Aluminum (6061, 6063, 7075), Stainless Steel (304, 2205, 2507, 17-4 PH, 904L), Nickel Alloy (Alloy 400, K-500, 718, 625, 601, 600, 825, 800, 800H, 800HT, C22, C276), Titanium, Copper, Brass, etc.

Some important characteristics of the most popular machining metal and alloy materials include:

stainless steel materials for custom made fasteners production

Stainless Steel

Stainless steels can be classified based on their crystalline structure. This includes austenitic, ferritic, martensitic, duplex and super duplex.

special nickel alloy materials for custom made fasteners production

Special Nickel Alloy

Materials such as: Alloy 400, K-500, 718, 625, 601, 600, 825, 800, 800H, 800HT, C22, C276, B, B2, B3, C4, C2000, G-35, 230, X750, 617, 925, GH series.

titanium materials for custom made fasteners production


Titanium fasteners are widely used in special fields, such as heat exchangers, aerospace and defense, nuclear, energy and valves systems.

Aluminum Alloy

Aluminum alloy is a lightweight metal with an excellent strength-to-weight ratio, making it ideal for applications in which metallic-level strength is required but mass is still a concern.

brass materials for custom made fasteners production


Brass is a versatile copper alloy that retains some of the benefits of pure copper but also improves on some of its attributes. Brass is a mechanically stronger and lower-friction metal, and offers better corrosion and wear resistance than basic copper.

copper materials for custom made fasteners production


Copper material is well known for its electrical and thermal conductivity. It is very resistant to corrosion and is also inherently antimicrobial. The energy, automotive, medical, and aerospace industries make use of copper specifically for these properties.
