C87400 copper strip is a lead-free silicon-brass alloy known for its excellent machinability and good mechanical properties. Its unique composition, which includes silicon and a carefully balanced copper-zinc ratio, provides superior cutting and forming characteristics comparable to traditional leaded brasses. This makes it an ideal material for high-speed automatic machining processes, such as those used in producing precision components like valves, fittings, and plumbing hardware.
In addition to its machinability, C87400 copper strip offers good corrosion resistance and moderate strength, ensuring reliable performance in various environments, including mildly corrosive and wet conditions. The material is also environmentally friendly due to its lead-free nature, meeting strict health and safety standards. Furthermore, it exhibits good solderability and can be readily joined using standard techniques, making it a versatile choice for applications in the automotive, electronics, and sanitary fitting industries.
