Improved zinc base alloys containing titanium

摘要

The invention includes the discovery that the addition of titanium to a zinc based alloy containing epsilon as a primary phase results in an increase in tensile and compressive strength of the alloy. The alloy can be used in gravity, permanent mold or die casting processes to mold components or tooling. In a preferred embodiment, 0.01-0.1 weight percent titanium is added to a zinc based alloy containing 3-12 weight percent copper, 2-5 weight percent aluminum, minor constituents and the balance zinc.
