So, its significantly better than 6061... (7005 is about 5.5% 'stronger' (in terms of Tensile strength at yield) than 6061)www.dahon.com said:
I think 'U6' is just a trade name (like 'Araldite' for example). Ive found an aluminium alloy that has very similar properties to those claimed by Echo and Dahon (Folding bikes). It is 'UltrAlloy® 6020-T9 Aluminum' (which is where the 'Ultra' bit comes from? And the '6' from the series of alloy? I dunno... just an informed guess)
All in all sounding pretty sweet for bike frames.www.MatWeb.com said:
