What grade ally?

[Chris152]

We need to make up a pair of these handlebar clamps - what grade ally is best for the job?



Thanks for any thoughts.

Go and look at manufacturers of aftermarket yokes and clamps.

Ignore the 'billet' and 'aerospace' marketing BS on their websites and identify the material grade they use.

Pick the same grade of material.

The people doing this work may use inflated terms to sell their items but they would not stay in business long if the stuff they use snaps and ends up with someone killed.

I've been through a couple of pages of Google search and the only one that stated anything about the ally described it as 'Airplane grade"!

They're probably a 6000 series alloy, but it's not going to make a lot of difference really.

Whatever you can get.
Usually something like 6082.

They discuss various components and the allys made from in this article.

I've used 6082 T6 without it causing a problem, machines nicely and anodises if required.

6082 T6 H30. Thats what I used to make motorcycle yokes, risers and clamps etc.

6082 if you're english
6061 if you're american

7xxx series if you want high strength (not generally weldable)

Would you know if it has any detail on sulphur based free machining steels like EN16M/ 605m36, EN8M?

 

[Chris152]

OK, thanks all - 6082 it is. And we'll do some reading Really appreciate the replies.
