Abstract

A liquid die forging aluminium alloy and a preparing method thereof are disclosed. Raw materials of the aluminum alloy include 45-50% by mass of waste automobile aluminum wheels, 25-30% by mass of waste automobile aluminum gearbox shells, 10-12% by mass of waste aluminum pop cans and 5-8% by mass of waste aluminum electric wires and cables, with the balance being aluminium ingots. Waste aluminum is adopted as the main raw material. The liquid die forging aluminium alloy having high performance is directly regenerated through optimizing composition of the waste aluminum raw materials, thus increasing the using value of the waste aluminum and reducing the production cost of the liquid die forging aluminium alloy. The produced liquid die forging aluminium alloy has advantages of high strength and good plasticity, can be used as load-bearing structure parts of automobiles, electronic products, mechanical equipment, aviation and spaceflight, weapon equipment, and the like, and has a wide application prospect.

Description

technical field [0001] The invention belongs to the field of alloy preparation, and in particular relates to a liquid die forging aluminum alloy and a preparation method thereof. Background technique [0002] Liquid die forging technology is a metal forming process that has both casting characteristics and is similar to die forging. It directly pours a certain amount of molten metal into the mold cavity, and solidifies and forms under the action of continuous mechanical static pressure. Liquid die forging technology can eliminate the shrinkage cavity formed by solidification and shrinkage, and obtain high-strength parts with fine and uniform grains and dense structure. Liquid die forging technology is widely used in automobiles, electronic appliances, mechanical equipment, aerospace and weaponry and other fields. [0003] With the development and wide application of liquid die forging technology, the demand for high-performance liquid die forging aluminum alloys is also inc...
