Abstract
There is disclosed a method of producing an aluminum alloy for automotive parts, comprising adding a scrap of an aluminum wrought alloy or a pure aluminum ingot to an aluminum alloy casting scrap, melting the mixture to dilute impurities, and if necessary, adjusting elements of the resultant. According to the above method, aluminum alloy casting scraps, which contain large amounts of impurities and have been difficult to recycle into other articles until now, can be converted to an aluminum alloy material that is applicable as a wrought material usable as a higher-grade material.
