ABSTRACT:
An improved continuously castable zinc base alloy comprises 4-10 percent by weight aluminum, 1-6 percent by weight copper and 0.02-0.04 percent by weight magnesium, the balance being zinc. One preferred composition consists essentially of 9.5 percent by weight aluminum, 5.5 percent by weight copper and 0.03 percent by weight magnesium, the balance being zinc. Another preferred continuously castable zinc base alloy consists essentially of 6.5 percent by weight aluminum, 3.8 percent by weight copper and 0.03 percent by weight magnesium, the balance being zinc. The zinc alloys of this invention exhibit highly favorable levels of tensile strength as well as tensile strength stability characteristics.
