CC491K Bronze Casting
CC491K Bronze Casting is a leaded tin bronze specified under EN 1982 CC491K (CuSn10Pb2), equivalent to DIN 2.1052. It combines the strength of a 10% tin bronze with improved machinability from the 2% lead addition, making it suitable for precision bearing and valve applications. Indicative price: US$ 10.20/kilogram.
