Abstract

Disclosed is an aluminum alloy for die casting which comprises 1.0 weight % to 2.0 weight % of magnesium (Mg), 0.5 weight % to 1.6 weight % of iron (Fe), and 0.5 weight % to 0.9 weight % of silicon (Si), with the remainder being aluminum (Al) and inevitable impurities.

First claim

The invention claimed is:

1. An aluminum alloy for die casting, consisting essentially of:
1.0 weight % to 2.0 weight % of magnesium (Mg);
1.0 weight % to 1.2 weight % of iron (Fe); and
0.5 weight % to 0.56 weight % of silicon (Si),
wherein the remainder are aluminum (Al) and inevitable impurities,
wherein the aluminum alloy has a thermal conductivity of 160 W/mK or more.

2. The aluminum alloy of claim 1 , wherein a difference (ΔT) between the solidus temperature and the liquidus temperature of the aluminum alloy is not more than 70° C.

3. The aluminum alloy of claim 1 , wherein the aluminum alloy has a tensile strength of 140 MPa or more.
