We report a new Mg-Sn-Zn-Al-based alloy that is suitable for extrusion to give a high-strength. The extruded alloy exhibited high yield strengths of 308 MPa in tension and 280 MPa in compression, to give a tension to compression ratio of 0.9. The extruded alloy consists of coarse and fine-grains with a basal texture, which gives rise to the high tension to compression ratio. The fine microstructure is attributed to the dynamic recrystallization and precipitation that occur during the extrusion.
