Alloy Frames

(1/1)

HEYWOOD BMX:
 :) I have noticed that most allloy frames are either 7005 or 6061,please can someone elaborate on the difference? From experience I feel that 7005 frames seem to have a lot more rear end flex than those made from 6061.Is this true,or just me???

                Thanks,

                James

i find alli frames very stiff and ive had 7005 and 6061  much stiffer than steel , good for bmx frames , but not as strong as steel ,

Dingobmxer:
I think 6000 series alloys have to be heat treated and 7000 series dont, hense the difference

 :) DINGO :)

zed4130:
