Disclosed are an aluminum alloy composition for die casting and a method of heat treating the same. The aluminum alloy composition contains precipitation of an Mg&#x2014;Zn-based strengthening phase through heat treatment to thus enhance strength thereof.

Aluminum alloy for die casting and method of heat treating the same

A method for surface treatment of aluminum alloys for forms an oxidation film in the aluminum alloys for casting by adding a metallic anion compound to an electrolytic solution. The method can prevent cracks from occurring on a surface of the aluminum alloys for casting at the time of applying an anodizing method.

Electrolytic solution and method for surface treatment of aluminum alloys for casting

A core pin is provided that prevents a molten metal from flowing into a pipe and a casting device using the same is also provided. The core pin specifically contacts a first end of the pipe inserted into a mold to close the end of the pipe, to thus prevent the molten metal from flowing into the pipe.
