Abstract: An alloy for use in die casting having improved thermal conductivity and strength includes at least about 86.0 percent aluminum by weight, from about 9.70 to about 10.70 percent silicon, by weight, from about 0.40 to about 0.70 percent iron, by weight, about 0.25 percent copper, by weight, about 0.50 percent manganese, by weight, from about 0.10 to about 0.20 percent titanium, by weight; and from about 0.010 to about 0.025 percent strontium, by weight.
