C85400 Solid Copper Wire

C85400 is a typical leaded brass wire, renowned for its exceptional machinability. The uniformly distributed lead content in the material acts as a natural chip breaker and lubricant during machining, enabling easy and rapid cutting on high-speed automatic lathes. This not only improves machining efficiency and produces a smooth surface finish, but also effectively protects tool life, extending tool life. Therefore, it is known as “fast-cutting brass” and is ideal for manufacturing precision hardware.

In addition to its excellent machinability, C85400 also possesses excellent comprehensive mechanical properties and formability. It boasts higher strength and hardness than ordinary brass while retaining excellent wear and corrosion resistance. Furthermore, the alloy exhibits excellent castability and hot and cold workability, enabling it to be formed through a variety of processes, including casting, cold heading, and forging. It is widely used in the manufacture of complex structural components such as gears, valves, pipe fittings, screws, and watch parts.
