Abstract

The invention discloses an aluminum alloy casting material including multiple kinds of metal and a manufacturing process of the aluminum alloy casting material. The aluminum alloy casting material ischaracterized in that the casting material comprises, by weight, 15-25 parts of aluminum, 8-14 parts of iron, 6-11 parts of copper, 8-12 parts of zinc, 4-8 parts of manganese, 3-7 parts of magnesium,2-6 parts of silicon dioxide, 2-6 parts of chromium, 1-3 parts of titanium, 1-3 parts of nickel, 1-3 parts of tin, 2-4 parts of cadmium, 0.5-1.5 parts of mixed rare earth, 5-9 parts of divinyl polyamine, 4-8 parts of crystalline flake graphite and 2-4 parts of a casting nucleating agent. According to the aluminum alloy casting material including the multiple kinds of metal and the manufacturing process of the aluminum alloy casting material, the material comprises the metal elements of manganese, magnesium, chromium, titanium, nickel, tin, cadmium and the like, the mixed casting process is adopted, and the produced casting material is low in mass, large in strength and good in mechanical performance, can bear large mechanical strength and can be widely applied to the fields of bus supports, valve castings, brake air chamber supports and the like.

Description

technical field [0001] The invention relates to the technical field of casting, in particular to an aluminum alloy casting material containing multiple metals and a production process thereof. Background technique [0002] Casting is a method of smelting metal, making a mold, injecting molten metal into the mold, cooling and solidifying to obtain a metal part blank with a certain shape, size and performance. [0003] Most of the raw materials used in traditional casting castings are only a single metal, or several metals are melted and mixed, but the weight is heavy, the strength is average, and the mechanical properties are low, especially in high temperature, high pressure, and corrosive extreme environments for a long time. In the middle, the working life is short, and it is prone to deformation and even fracture. [0004] Chromium, titanium, tin, cadmium and other metals can improve the mechanical strength of aluminum alloys, making castings resistant to high temperatur...
