Does anyone know where I can get 6061 or 7075 in metric hex sizes?
Heck I can't even find it in inch sizes without buying a large quantity.
I have been machining it myself from round stock, which is proving to be time consuming and wasteful.
The sizes I need right now are 14 and 17mm across the flats.
Any help would be appreciated.

If you find a source I would be glad to know it; I have tried and failed to get 6061 in hex. 2011 and 2024 is available in mill run quantities and of course if you want to spring for a die and take a minimum order of a thousand pounds or so it is possible to get 6061 but that was about a twenty year supply based on my consumption.

Thanks for the link it may be useful. They do not list 6061 but have 6060 which as far as I can discover is maybe not quite as strong. I found a reference that said 6060 was similar to 6063 and that 6063 was lower strength than 6061. It seems 6060 is used in many countries outside North America instead of 6061.


EDIT: This gives a very good simple explanation of aluminum alloys.
