ABSTRACT:
A Zn--Cu based alloy is disclosed including from about 11 to about 50 wt. % of Cu, from about 0.1 to about 10 wt. % of Al, from about 0.01 to about 1.0 wt. % of Mg, and from about 0.001 to about 0.1 wt. % of at least one member of the group consisting of Ti, Pb, Sn, Cd, Ni, Mn, Cr, Fe and mixtures thereof; and the balance being Zn. The Ti component may be added via an Al--Ti alloy. This alloy yields high-part-number castings especially useful in the automotive parts field.
