ABSTRACT:
A copper base alloy capable of forming a microstructure comprising a plurality of discrete particles in a surrounding metal matrix having a lower melting point than the particles. The alloy consists essentially of from about 3% to about 6% nickel, from about 2% to about 4.25% aluminum, from about 0.25% to about 1.2% silicon, from about 5% to about 15% zinc, up to about 5% iron and the balance essentially copper. When iron is included in an amount from about 3% to about 5% and zinc is restricted to a range of from about 8% to about 10%, the alloy is capable of forming the desired structure in the as-cast condition using a process which does not include stirring during casting.
