Patent ID: 7967928

Claim:
A method of forming an extruded structural component comprising: extruding a magnesium alloy material through a die orifice, wherein said magnesium alloy material is capable of an extrusion speed of greater than or equal to about 305 mm per minute at about 360° C., wherein said alloy material has a composition comprising aluminum (Al) at about 2.5 to about 3.5 wt. %; manganese (Mn) at about 0.2 to about 0.6 wt. %; zinc (Zn) less than an impurity level of 0.22 wt. %; one or more trace impurities other than zinc (Zn) collectively less than about 0.1 wt. %, including strontium (Sr) at less than an impurity level of 0.02 wt. %; and a balance of magnesium (Mg) to form the extruded structural component having a yield strength of at least about 150 MPa and an elongation of greater than or equal to about 10% at room temperature.
