A newly recycling process for video camera components of AZ 91 D magnesium alloy used for professional market was developed by melting and casting processes in order to satisfy the JIS specifications for recycled AZ 91 D magnesium alloy ingot. Various quantities of Mn were added to the melt in order to avoid contamination by impurities such as Fe, Ni and Cr from paints. Composition analysis and mechanical properties and corrosion resistance of the recycled ingots were also examined. Recovery ratio of the recycled ingots is in the range of 60 % to 75 %. Chemical composition and tensile properties of the recycled ingot with Mn addition of more than 0.23 % is satisfied by JIS specification except for Cu content. Tensile strength and 0.2 % proof stress of the recycled ingots increase with increasing Mn content. The recycled specimens with Mn addition of more than 0.23 % almost exhibit the same level of corrosion resistance as the virgin ingot of AZ 91 D magnesium alloy.

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.
