PROBLEM TO BE SOLVED: To provide a copper base alloy having forgeability characteristic of brass contg. Pb, more inexpensive in the raw material cost and having excellent dezincification resistance and moreover to provide a copper base alloy suitable for apparatus concerning to warm water, electric and machine parts or parts for ships. SOLUTION: As for apparatus concerning to warm water using a copper base alloy excellent in corrosion resistance and hot workability, a copper base alloy having a compsn. contg., by weight, 59.0 to 62.0% Cu, 0.5 to 4.5% Pb, 0.05 to 0.25% P, 0.5 to 2.9% Sn, 0.05 to 0.30% Ni, and the balance Zn with inevitable impurities is used as the material to produce apparatus concerning to warm water. |
