Copper base alloys consisting essentially of 1.0 to 4.0% tin, 0.01 to 0.20% phosphorous, 0.01 to 0.80% iron, 0.1 to 12.0% zinc and the balance essentially copper, including phosphide particles uniformly distributed throughout the matrix. The alloy is characterized by an excellent combination of physical properties. The process of the present invention includes homogenizing, rolling, process annealing and stress relief annealing.
