ALUMINUM ALLOY FOR DIE CASTING

摘要

The present invention relates to an aluminum alloy for die casting, and more specifically, to an aluminum alloy for die casting comprising 1.0-5.0 wt% of Mn, 0.5-1.5 wt% of Zn, 1.0-2.0 wt% of Zr, 0.5-1.5 wt% of Cu and 85-97 wt% of aluminum. According to the present invention, the aluminum alloy for die casting does not generate surface spots due to the smutting of silicon when anodizing after molding a product differently from a conventional aluminum alloy for die casting and enables a uniform and aesthetically pleasing color to be implemented, can improve the durability of a die casting product because of being able to increase the adhesive strength of a film, and is harmless to the human body and environmentally friendly because no heavy metals known to be harmful to the human body are used.
