铝合金及其制备方法

ALUMINUM ALLOY AND METHOD OF PREPAIRING THE SAME
Abstract:
An aluminum alloy contains 1-4wt％ of Mn, 0.1-5wt％ of Mg, 0.002-0.5wt％ of a rare earth element, 0-2wt％ of Co, 0-1.5wt％ of Fe, 0-1wt％ of Ti, 0-1wt％ of Cu, 0-1.6wt％ of Zn, 0-0.5wt％ of Si, and 82.9-98.898wt％ of Al, based on total weight of the aluminum alloy. The rare earth element contains La. Based on the total weight of the rare earth element, the content of La in the rare earth element is from 20wt％ to 100wt％. A method of preparing an aluminum alloy, a method of coloring a surface of an aluminum alloy and an aluminum alloy product are also provided.
