  • Aluminum Casting Alloy with Improved High-Temperature Performance
    Publication number: 20160319400
    Abstract: An aluminum alloy includes, in weight percent, 0.1-0.25 Si, 0.10 max Fe, 2.0-3.4 Cu, 0.9-1.2 Ni, 1.3-1.8 Mg, 0.25 max Ti, and one or more dispersoid forming elements, the balance being aluminum and unavoidable impurities. The alloy is suitable for casting, and may be formed into a cast alloy product. Additionally, the alloy exhibits excellent high temperature mechanical properties, particularly high temperature fatigue strength, as well as good corrosion resistance.
