US Patent 7967928 Methods of extruding magnesium alloys

Methods of extruding magnesium-based casting alloys are provided. The magnesium alloys have relatively high strength and castibility, as well as an improved ductility and extrudability for wrought alloy applications. The magnesium-based wrought alloy comprises aluminum (Al) of between about 2.5 to about 3.5 wt. %, manganese (Mn) of less than about 0.6 wt. %, zinc (Zn) of less than about 0.22 wt. %, other impurities of less than about 0.1 wt. %, and a balance of magnesium (Mg). The disclosure provides various methods of forming extruded structural components, including automotive components, and methods of forming such wrought alloys.
