Leading wheel manufacturer Alcoa has developed an alloy wheel that makes dirt-engrained wheels a thing of the past. With Dura-Bright technology, it is claimed to be easy to remove dirt and brake dust with minimal cleaning and using only water. The wheels have a polished finish that will neither chip, fade or "yellow" like traditional wheel finishes. Penetrating the wheel itself, the Dura-Bright technology will not crack, peel nor corrode, ensuring the wheel looks good for many years.
The metal treatment technology, proven to last in the tough truck market, will also make life easier for consumers when they come to sell their car. In addition, all Dura-Bright wheels are produced by Alcoa's forged engineering expertise. Alcoa forged aluminum wheels provide increased strength and durability as compared to cast aluminium wheel in crush tests. A forged wheel also reduces unsprung weight on a car, maximizing vehicle performance, including more responsive steering and braking performance, while reducing weight compared to a similar cast aluminum wheel by over 20%.
The first European application will be available in winter 2008 on the new Audi A6. While there are already several US domestic applications for the technology, this is the first time a European manufacturer has offered it on their products.
