Description

technical field [0001] The invention relates to an aluminum alloy material suitable for the automobile industry. Background technique [0002] The safety and reliability of a car largely depends on the performance and service life of the wheels used. Aluminum alloy wheels stand out in the automotive industry due to their advantages of light weight, fast heat dissipation, good shock absorption performance, long tire life, safety and reliability, beautiful appearance, colorful patterns, precise size, good balance, and easy manufacturing. The potential is huge. At present, cast aluminum alloy wheels all over the world are produced by A356 alloy series alloys. With the rapid increase in the output of aluminum alloy wheels (A356) and the continuous development of industrial mass production. During the production process, problems such as limited effect of deterioration treatment and unstable casting quality gradually emerged. Contents of the invention [0003] The techn...
