C18200 copper plate is a copper alloy containing chromium and zinc with good electrical conductivity, wear resistance and corrosion resistance. It has high strength and hardness at room and high temperatures (400°C), and after age-hardening treatment, its strength, hardness, electrical conductivity and thermal conductivity are significantly improved, with an electrical conductivity of not less than 80% IACS.
Due to its excellent performance, C18200 copper plate is widely used in aerospace, electronic communications, precision medical equipment and electrical equipment in high temperature conductive wear parts. For example, motor rectifiers, collector rings, high-voltage switches, welding machine electrodes, etc., becoming one of the indispensable materials in high-end manufacturing.
