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.
