    Magnesium Alloy Process Developments and Applications

    Editor’s Note: Although the focused patent surveys in Light Metal Age have generally covered select aluminum technologies, magnesium alloy technology has generally been sidelined. Nevertheless, magnesium is a major alloying master alloy in aluminum casthouse production and critical to the reduction of light metals, such as titanium and beryllium. Therefore, this patent survey aims to […]
