Abstract

The invention discloses a preparation method of an impact resistant alloy for die casting. The preparation method comprises the steps as follows: manganese, magnesium, titanium, nickel and zinc in a ratio are selected, mixed and put in a smelting furnace for fusion treatment at a temperature of 780-820 DEG C, and a mixed solution is obtained; a refining agent is added to the smelting furnace, the mixture is sufficiently stirred and heated continuously to 850-870 DEG C; aluminum and silicon are put in the smelting furnace, argon is introduced into the smelting furnace after sufficient stirring, the mixture is subjected to heat insulation and left to stand for 10-20 minutes, and an alloy solution is obtained; the alloy solution is conveyed to a die casting machine for stamping forming, and the impact resistant alloy for die casting is obtained finally after cooling. With adoption of the method, the alloy can have the characteristics of light weight, high strength, strong impact resistance, good plastic property, high quality and long service life; the preparation process is simple, and the cost is lower.

Description
