Alcoa's aerospace-technology aluminium wheel blanks used for Solomon Alsberg Audi wheel

Alcoa has extended the range of lightweight wheel forgings supplied to Solomon Alsberg for their exclusive high-performance alloy wheels. The aerospace-derived metallurgy of the Alcoa blanks allows Solomon Alsberg to create a wide range of ultra-stylish wheels that improve vehicle performance and dynamics as well as reducing fuel consumption and emissions.

The 20 inch blanks supplied within this programme are produced from billets of 6061-T6 aluminium, using the same technology as the wheels it produces for the Boeing 747. The superior strength of this alloy in one-piece wheels allows a significant weight saving over cast or multi-piece wheels. The forging process aligns the metal grains uniformly along the contours of the wheel, allowing less material to be used thus reducing weight. Alcoa’s weight-optimised 20 inch forged wheel can weigh as small as 7.5kg – up to 7kg less than a typical cast alloy wheel of the same diameter.
