Malleability, resistance to stress corrosion cracking resistance and dezincification corrosion in excellent copper-based alloy

摘要

Mass % in, Cu: 61.0 - 63.0%, Pb: 1.3 - 2.0%, Sn: 1.8 - 2.8%, Sb: 0.05 - 0.25%, P: It possesses machinability and the strength where the remainder consists of Zn and the impurity with 0.04, - 0.15 can be satisfied industrially, it designates the offer of the copper basic alloy which possesses malleability, resistance stress corrosion crack Characteristic and the resistance dezincification corrosiveness which at the same time are superior as purpose.
