Alex. Posted December 7, 2010 Report Share Posted December 7, 2010 Is there an easy way of identifying the grade of aluminium of a piece of bar? I obtained a length of 44mm ally bar from a local engineering firm, but didn't have the foresight to ask what grade it was. I intended to use it to make some wheel spacers for the fork swap on my bike, but all the talk of the right materials in other threads has me slightly concerned! Can I just go ahead and use the spacers? Does the grade matter if there is no real stress involved, just some compressive forces? The threaded spacer will be made from steel... Alex.

porter_jamie Posted December 7, 2010 Report Share Posted December 7, 2010 i should think it will be ok for wheel spacer. i will probably be he30 or 6082t6. you could ring them and ask! Link to comment Share on other sites More sharing options...
Evilchicken0 Posted December 7, 2010 Report Share Posted December 7, 2010 Would there be a difference in weight / mass ??? Link to comment Share on other sites More sharing options...
porter_jamie Posted December 7, 2010 Report Share Posted December 7, 2010 density between he30 and a 2000 series is 0.1g/cm-3 Link to comment Share on other sites More sharing options...
Evilchicken0 Posted December 7, 2010 Report Share Posted December 7, 2010 density between he30 and a 2000 series is 0.1g/cm-3 So the difference is 15.2g per 100mm 44mm bar = 2.2cm radius (squared) x pie = 15.2 cmsq x 0.1g x 1cm = 1.52g per 1cm length um maybe .... it's been a while since I did any mathematics Link to comment Share on other sites More sharing options...
