Good Day all

Is it possible to substitute 6082 instead of 6061 t6. Not sure of the temper of the 6082 ,will find out. The reason is 6082 is locally available,otherwise it is an import.

thanks

From what I read it is comparable, some specs showing slightly less strength and some showing slightly more. using the same T6 temper seems prudent. Doubtless your 6082 supplier can give you answers if they are ethical enough to offer facts before a sales effort. OH, and welcome to the forum quickcut !

If it is ok, will your Aviation Administration let you just change, or will you need engineering docks to say its ok? In the US, we dont, but the Europeans tend to need something to back it up.

Thank you for the replies and link as well as the welcome. I will check the temper in the morning, But perhaps I should check with the plans supplier first as well as the local regulations. I believe our local CAA is getting quite sticky .

Thanks again

6082 is less pliable and ductile. It has a much greater content of Si and Mn with less Cu and Fe. In other words, it's stiffer/more brittle and isn't as easy to shape/form. Likewise, it is mostly a EU distributed alloy. The US military has moved from 6061 more toward 7075 T73 over the past decade or so, which has better elongation properties is less brittle and forms better.
