The Alcoa Dura-Bright EVO wheel is designed to be resistant to corrosion primarily caused by road salts and weather elements, and resistant to chemicals found in the toughest truck cleaning agents. According to the company, the Dura-Bright wheel allows brilliant shine to last even after years of use, without the need for polishing. Dura-Bright is not a coating, but rather a surface treatment that penetrates the aluminum and becomes an integral part of the wheel, ensuring what happens on the road stays on the road. All Alcoa wheels are made from one piece of forged aluminum.
