It was intended by a recycling process of professional use video camera scraps to obtain ingots that satisfy the JIS for chemical composition of AZ91D magnesium alloy. The paint finishing was removed firstly by a shot blast method and the scraps were melted. The removal decreases the generation of toxic gases during heating stage. The recovery rate of metals is remarkably improved to be more than 80% due to depression of Mg oxidation accompanied by the paint combustion. The chemical composition of recycled ingots meets the JIS and such impurities detrimental for corrosion resistance as Fe, Ni and Cr are little contained. The corrosion resistance of recycled specimens exhibits the same level as a virgin AZ91D magnesium alloy. Their tensile properties satisfy the JIS for castings, and their 0.2% proof stress is higher than that of specimens recycled from non-professional use video cameras.
