C85800 Thin Copper Plate

C85800 is a high-performance nickel-brass sheet renowned for its balanced and excellent overall performance. Its most prominent feature is its exceptional machinability; the lead content effectively breaks chips and lubricates cutting tools, making it a prime example of a free-machining alloy, ideal for high-speed automated production. Simultaneously, the added nickel significantly enhances the alloy’s strength, hardness, and wear resistance, resulting in mechanical properties far superior to ordinary brass. Furthermore, it exhibits good corrosion resistance, particularly against dezincification corrosion, and demonstrates stable tolerance to atmospheric conditions, seawater, and various non-oxidizing media.

For these reasons, C85800 copper sheet is widely used in the manufacture of complex parts requiring high precision, durability, and reliability. It can be found in critical industrial sectors, such as synchronizer gear rings in automotive manufacturing, high-strength gears in the machinery industry, pump and valve components, and valves and fittings in high-pressure environments. It successfully combines excellent machinability with superior performance, reducing production costs and extending the service life of end products, making it an ideal material choice for many wear- and pressure-bearing critical components.
