摘要： Aluminum alloys described herein include silicon, iron, copper, manganese, magnesium, and chromium. In various implementations, the aluminum alloys also include one or more of zinc and titanium. Typically, a total amount of iron and manganese in the aluminum alloys is no less than 0.28% by weight and no greater than 0.45% by weight, and the grains in the aluminum alloys have an average grain length of no greater than 6 mm. Aluminum alloy billets can be forged for wheel production at selected temperatures.

摘要： Aluminum wheels include a rim and a disc having a mounting portion. The mounting portion includes an inner mounting face and an outer mounting face. The mounting portion also includes a coarse grain region and a fine grain region. The coarse grain region can be adjacent, and at least partially form, one of the inner mounting face or the outer mounting face. The coarse grain region includes aluminum alloy grains of a first average grain length that is greater than 1 mm. The fine grain region extends between the coarse grain region and the other of the inner mounting face or the outer mounting face. The fine grain region includes aluminum alloy grains of a second average grain length that is less than 0.5 mm.
