Wiki says
" * 1000 series are essenitally pure aluminium with a minimum 99% aluminium content by weight and can be work hardened
* 2000 series are alloyed with copper, can be precipitation hardened to strengths comparable to steel. Formerly referred to as duralumin, they were once the most common aerospace alloys, but were susceptible to stress corrosion cracking and are increasingly replaced by 7000 series in new designs.
* 3000 series are alloyed with manganese, and can be work hardened
* 4000 series are alloyed with silicon. They are also known as silumin
* 5000 series are alloyed with magnesium, derive most of their strength from solution hardening, and can also be work hardened to strengths comparable to steel
* 6000 series are alloyed with magnesium and silicon, are easy to machine, and can be precipitation hardened, but not to the high strengths that 2000, 5000 and 7000 can reach.
* 7000 series are alloyed with zinc, and can be precipitation hardened to the highest strengths of any aluminium alloy.
* 8000 series are a miscellaneous category"

You know, that was one of the most useful pages I've ever found on Wiki. Interesting that Whyte make such a hoo-ha about their magnesium enriched 6061 alloy isn't it?

Very basically, 6061 is easier to work, 7005 is harder to work but stronger. Its how the frame is made that counts.
