CC480K Bronze Casting
CC480K Bronze Casting is a leaded tin-zinc bronze specified under EN 1982 CC480K (CuSn3Zn8Pb5), equivalent to DIN 2.1080. It contains nominally 84% copper, 3% tin, 8% zinc, and 5% lead, offering excellent castability, pressure tightness, and machinability for general engineering fittings and valve bodies. Indicative price: US$ 8.20/kilogram.
