CC482K Bronze Casting
CC482K Bronze Casting is a leaded tin-zinc bronze specified under EN 1982 CC482K (CuSn7Zn2Pb3), equivalent to DIN 2.1090. Containing approximately 88% copper, 7% tin, 2% zinc, and 3% lead, CC482K delivers higher strength than CC481K and is widely used for pressure-tight castings and moderate-duty bearings. Indicative price: US$ 8.80/kilogram.
