Cu-92 is copper and it's number. Cu-92 was a type of Al with copper used by Giant up to about 2001, which was then replaced by their Aluxx series. Copper in in Al makes it a harder alloy, generally speaking.

"Pure" is just Yeti's name for the tubing they use. Any company can do that also. Hell, the tubing of several well known and instantly recognizable frames was on display at Eurobike's Taiwan section in the booths of Taiwanese tubing manufacturers.

ummm... yes i know that it is aluminium alloy... i ws hoping for a little more detailed info, eg my arc has a couple of 7000sc tubes and i assume the rest is 7005 easton stuff, so what i mean does anyone know what sort of aluminium it is?

also, due to being sleepy, i know what CU92 it, what a should have asked is what is AN6 (old giant tomacs, vs new tomac tomacs)... its all just out of interest.

.
If it is a Taiwan sourced frame, then it is unlikely that it is Easton sourced Scandium or Ultralite AL tubing. Generic SC alloy has been available for some time in Taiwan as seen in Kona's, Salsa's, Voodoo's and Brodies. The factories there are just as adept in butting and tubing manipulation (possibly better) then Easton. My understanding before I bought my Arc was that just the downtube is SC alloy.

Back before the ARC was made in Taiwan and made in USA the Easton Stickers stood proud on the frame. Guessing 2005 and earlier, please correct me if I am wrong.

AN6 was some 6000 series heat treated to t6 levels. Last time I saw this going around, Tomac and Litespeed were using them in various frames and tehy were all failing.

Yeti's pure tubing on the current 575 is 7005 series aluminum. Although I don't really know what that means either. I read it either on their website or in the catalog. I've seen other manufacturers touting 7005 aluminum too, it must be a damn good alloy.
