Magnesium alloys containing, by mass percent, Al: 10.0 to 13.0%, Si: 0.3 to 1.5%, Mn: 0.1 to 1.0%, and, if desired, Zn: less than 0.8%, the rest being Mg and unavoidable impurities. Neither cracking by the casting is invited nor the mechanical property is spoiled, and the fluidity can be notably improved, and it is possible to make products small in thickness and light in weight.

Magnesium alloys excellent in fluidity and materials thereof

A method of coating a powder lubricant in a metallic injection molding machine having a die composed of a stationary die ( ) and a movable die ( ), a sprue hole ( ), runner groove ( ), gate hole ( ) and cavity ( ) being formed on parting faces (P) of these dies ( ), a cold plug catcher ( ) communicating with the sprue hole ( ) when the movable die ( ) is fastened to the stationary die ( ) being formed in the movable die, the method of coating a powder lubricant in a metallic injection molding machine comprising the step of coating the powder lubricant from the cold plug catcher ( ) toward the cavity ( ) by decompressing the inside of the sprue hole, runner groove, gate hole and cavity from the cavity side.
