  • Publication number: 20260077404
    Abstract: Disclosed herein are systems and methods for providing lightweight alloy articles, for example, magnesium alloy battery enclosures for electric vehicles. In some embodiments, a magnesium alloy can progress through a production line configured to chip a magnesium alloy ingot, mix the chipped alloy with additional alloying elements, and melt and mold the alloy to form a magnesium alloy metal article. The article can then be finished, coated, and joined to another magnesium article and/or to a dissimilar metal to create the magnesium alloy article.
