C21000 copper plate, often referred to as Low-Leaded Red Brass, is a copper alloy renowned for its exceptional combination of electrical conductivity, thermal conductivity, and corrosion resistance. This alloy contains a copper content of approximately 88-89%, with the remaining composition comprised of copper, zinc, and lead. The small addition of lead enhances the machinability of C21000 copper, making it easier to work with for manufacturing a variety of components and parts.
The high electrical conductivity of C21000 copper plate makes it a preferred choice for electrical and electronic applications, where efficient current transmission is crucial. It is commonly used in the production of connectors, switches, and conductors in electrical systems. Furthermore, its good thermal conductivity properties make it suitable for heat transfer applications, making C21000 copper plates valuable in the creation of heat exchangers, radiators, and other thermal management systems. Its inherent resistance to corrosion also adds to its versatility, enabling its use in various environments where protection against rust and corrosion is vital, particularly in plumbing systems and marine applications.
