Abstract
The invention relates to high strength magnesium alloys used in 3C, transportation and sports products. Combining with reciprocating extrusion magnesium alloys with high aluminum content and low workability might be extruded to have homogeneous, uniform and fine-grained structure and thus become light-weight, low-cost, high-strength and superplastic magnesium alloys. The invented alloys mainly comprise 10.0 to 30.0 wt% aluminum and 0.5 to 4.0 wt% zinc in composition.
