PROBLEM TO BE SOLVED: To provide a copper base alloy suitable for many uses, and to provide a process of producing the copper base alloy. SOLUTION: A copper base alloy consisting essentially of tin in an amount from about 1.0 to 11.0% by weight, phosphorous in an amount from about 0.01 to about 0.8% by weight, iron in an amount from about 0.01 to about 0.8% by weight, zinc in an amount to 15% by weight as an optional element, and the balance essentially copper, including phosphide particles uniformly distributed throughout the matrix, is described. The alloy is characterized by an excellent combination of physical properties. The process of forming the copper base alloy described herein includes casting, homogenizing, rolling, process annealing and stress relief annealing. COPYRIGHT: (C)2005,JPO&NCIPI
