ABSTRACT:
An alloy system which exhibits improved resistance to stress relaxation at elevated temperatures utilizes additions of silicon or tin or mixtures of silicon and tin to a copper-zinc base to attain the stress relaxation performance. The composition and processing of this alloy system maintains at least 90% by weight alpha-phase within the alloy.
