CC483K Bronze Casting
CC483K Bronze Casting is a high-lead tin-zinc bronze specified under EN 1982 CC483K (CuSn7Zn4Pb6), equivalent to DIN 2.1093. With a higher lead content than CC482K, it offers improved machinability and anti-friction properties while maintaining adequate strength for bearing and bushing applications. Indicative price: US$ 8.80/kilogram.
