  • High strength, heat treatable aluminum alloy
    Patent number: 8357249
    Abstract: A high strength aluminum alloy is suitable for ultra thick gauge wrought product. The alloy can have 6 to 8 wt % zinc, 1 to 2 wt % magnesium, and dispersoid forming elements such as Zr, Mn, Cr, Ti, and/or Sc with the balance made of aluminum and incidental elements and/or impurities. The alloy is suitable for many uses, including in molds for injection-molded plastics.

  • Aluminum alloy sheet having high ultimate tensile strength and methods for making the same
    Patent number: 6383314
    Abstract: Aluminum sheets and methods for manufacturing aluminum sheets are provided. The present invention involves control of processing conditions in order to achieve a fine grain size (i.e. ASTM rating of 8.5 or greater) in the material prior to a final cold working operation. Also included within the scope of the present invention are products having a fine grain size which have strength levels above what can be obtained in 5××× alloys.
