Good results can be achieved by the application of vacuum magneto?dynamic system in preparing high strength wrought aluminum alloy. Compared with conventional technology,the hydrogen content in the prepared alloy decreases by 65% to 80%, resulting in the improvement of product quality and mechanical properties. The mechanical properties of ?142 mm semi ?continuous casting ingot prepared with second АД31 aluminum alloy as furnace burden are similar to those with new raw material.
