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.
