Copper base alloys possessing improved processability

摘要

A copper base alloy is disclosed which exhibits improved resistance to crack propagation during hot processing as well as good mechanical properties. The alloy comprises from about 4.0 to about 11.0% tin, from about 0.01 to about 0.3% phosphorus, from about 1.0 to about 5.0% of a material selected from the group consisting of iron and a mixture of iron and cobalt, up to about 0.4% chromium, balance essentially copper. The alloy of the present invention possesses a substantially non-dendritic grain structure in the cast condition which contributes to said resistance to crack propagation.
