In this study, as a process applicable also to recycling, the commercial magnesium alloy was used as materials, the obtained condensation thing was melted and cast in the high frequency power for vacuum melting furnace after vacuum distillation refining, and a mechanical property and corrosion resistance were investigated. The Vickers hardness number of the casting material of 4N becomes small 10 orders compared with the casting material and extrusion material of 3N. Although the ultimate tensile strength and 0.2% proof strength of casting material of 4N became small compared with the casting material of C-3N, growth becomes large about 5% with a little less than 20%. The corrosion rate of the casting material of 4N does not change with a commercial magnesium alloy, but becomes quite small compared with the casting material of C-3N.
