Aluminum alloy composition for die casting

Abstract

Disclosed is an aluminum alloy composition for die casting, including 0.85 to 1.2 wt % of copper, 0.15 to 0.2 wt % of silicon, 0.08 to 0.1 wt % of magnesium, 0.08 to 0.12 wt % of zinc, 1.5 to 2.5 wt % of iron, and inevitable impurities, with the remainder of aluminum. This aluminum alloy composition for die casting can exhibit superior mechanical properties and thermal conductivity, and can be prevented from sticking to a mold, thereby increasing die-casting efficiency.

AI Technical Summary

Benefits of technology

The present invention is an aluminum alloy composition that is intended for die casting. It has superior mechanical properties and thermal conductivity, and is also prevented from sticking to the mold, which increases the efficiency of the process.

Problems solved by technology

However, when the case is manufactured by pressing the aluminum plate, it is difficult to ensure space to mount parts inside the case and to form a rib for reinforcement and a boss for screw connection.

Furthermore, the design of the case is limited because there is a shape that cannot be formed by the pressing process.

However, the conventional aluminum alloy for die casting has relatively low mechanical strength and thermal conductivity, and the composition for aluminum alloy sticks to the mold during the die-casting process, undesirably lowering die-casting efficiency.
