| 摘要 |
Aluminum-based alloys for casting or wrought processing having improved combinations of properties, including improved high temperature strength, are provided. The alloys generally comprise copper, magnesium, silver, and titanium, along with scandium and/or cobalt. Zirconium, zinc, and/or vanadium may also optionally be present in the alloy. When cobalt is present in the alloy, nickel may also optionally be present. Cast and wrought products, as well as methods of making the same using the alloys, are also disclosed. |
