MAGNESIUM ALLOY

摘要

PROBLEM TO BE SOLVED: To provide a magnesium alloy good in extrudability, capable of accelerating extrusion rate as well as reducing extrusion load.SOLUTION: It contains Al of 0.1 to 3.0 wt%, Ca of 0.1 to 0.43 wt% and Mn of 0.15 to 1.2 wt% and the balance Mg with inevitable impurities, and conducts a homogenization treatment on a billet after casting at 450 to 500°C for 1 to 4 hours.SELECTED DRAWING: Figure 5
