<p>An aluminum-based casting alloy having improved corrosion resistance and casting characteristics for sand and permanent mold casting processes. The aluminum-based casting alloy contains from about 4.0 to about 7.0 percent silicon by weight, at least 87 percent aluminum by weight, from about 0.25 percent to about 0.5 percent manganese by weight, a maximum of 0.08 percent copper by weight, and from about 0.2 percent to about 0.8 percent iron by weight.</p> |
