Abstract

The invention discloses light environment-friendly aluminum alloy and a preparation technology thereof, and relates to the technical field of aluminum alloy casting. The light environment-friendly aluminum alloy comprises, by weight, 4.0%-6.0% of silicon, 0.2%-0.3% of ferrum, 2.5%-4.0% of copper, 0.2%-0.4% of manganese, 0.3%-0.5% of magnesium, 0.05%-1.0% of titanium, 0-0.5% of nickel, tin and lead, 0-0.2% of zinc, 0-0.05% of cadmium, mercury and chromium, the balance aluminum, 0-0.5% of other elements (the highest weight of each element accounts for 0.05%) and inevitable impurities. Accordingto the light environment-friendly aluminum alloy and the preparation technology thereof, the formula and the aluminum alloy preparation technology are reasonably designed, and the problems that an existing aluminum alloy production percent of pass is low, alloy product performance is poor, the technology is complex and manufacturing cost is high are solved.

Description

technical field [0001] The invention belongs to the technical field of aluminum alloy casting, and in particular relates to a light-weight environment-friendly aluminum alloy and a preparation process thereof. Background technique [0002] Casting aluminum alloy, as the name suggests, is based on aluminum, filling the mold in the molten state to obtain the aluminum alloy of a certain shape and size casting blank, casting aluminum alloy is used to manufacture parts with complex shapes, such as instruments, internal combustion engine pistons, aircraft and other shells body parts. Mainly use the characteristics of light weight and high strength. Cast aluminum alloys are widely used in machinery, automobiles, construction and other fields, and are new products that are promoted and applied by the state. [0003] The production of aluminum alloy castings is generally cast from outsourced finished aluminum alloy materials. The use of this material is limited by market condition...
