Abstract

The invention discloses a modification method for zinc alloy. The modification method for the zinc alloy comprises the steps that, firstly, materials are prepared from, by weight, 3.8-4.3% of aluminum, 2.7-3.3% of copper, 0.03-0.05% of magnesium, 0.05-0.08% of strontium, germanium, and the balance zinc, wherein the weight ratio of the germanium to the strontium is (0.5-0.8):1; secondly, the prepared materials are put in a smelting furnace to be smelted at the temperature of 600-680 DEG C; and thirdly, the smelted liquid alloy is burnt and cast at the temperature of 500-550 DEG C to obtain the zinc alloy. Compared with the prior art, the strontium and the germanium are used as modificators; by adjusting the use amount of the strontium and the germanium, the creep rate of the zinc alloy can be obviously reduced, and the creep resistance of the alloy can be improved.
