  • Aluminum-copper alloys containing vanadium
    Patent number: 10570485
    Abstract: New 2xxx aluminum alloys containing vanadium are disclosed. In one embodiment, the aluminum alloy includes 3.3-4.1 wt. % Cu, 0.7-1.3 wt. % Mg, 0.01-0.16 wt. % V, 0.05-0.6 wt. % Mn, 0.01 to 0.4 wt. % of at least one grain structure control element, the balance being aluminum, incidental elements and impurities. The new alloys may realize an improved combination of properties, such as in the T39 or T89 tempers.
    Type: Grant

  • Aging of aluminum alloys for improved combination of fatigue performance and strength
    Patent number: 9234266
    Abstract: Aluminum alloys having an improved combination of properties are provided. In one aspect, a method for producing the alloy includes preparing an aluminum alloy for artificial aging and artificially aging the alloy. In one embodiment, the artificially aging step includes aging the aluminum alloy at a temperature of at least about 250° F., and final aging the aluminum alloy at a temperature of not greater than about 225° F. and for at least about 20 hours.
