[QUOTE="Tob, post: 11256269, member: 83412"] It isn't about what you see but rather the process. It has been mentioned that... I believe the patent number for the Dura-Bright coating is 20100021757. As Alcoa puts it "the patented treatment actually penetrates the aluminum, forming a protective barrier that becomes an integral part of the wheel." The patent mentions that "the aluminum surfaces have a temperature in the region of 280 to 350° C" during this process. I'm no metallurgist (:-D) and I'm sure Alcoa has quite a bit of experience here, but if [i]improperly done[/i], you'll know when you cut the wheel in half. The specific grade aluminum alloy that Alcoa uses is 6061-T6.. (The red highlighted area is fodder for a different debate - see below) From [URL="http://www.alcoa.com/alcoawheels/north_america/en/news/releases/wheel_strength.asp"]here.[/URL] Grain structure defects, improperly done heat treatment, etc, could all play a role in the fact that the some wheels are distorting when they are cut in half. It would be interesting to hear James comment on any issue he has run into with other forged wheels, when cut. Of importance and directly from Alcoa... [ATTACH=full]256614[/ATTACH] [/QUOTE]
