WE43 Magnesium Alloy

WE43 is a high-performance rare-earth magnesium alloy primarily containing yttrium, rare-earth elements, and zirconium. It provides excellent elevated-temperature strength, creep resistance, corrosion resistance, and a good strength-to-weight ratio. Compared with conventional AZ-series magnesium alloys, WE43 is better suited for demanding aerospace, defense, and high-end industrial applications.
