Just a comparison for those that care (Derek you asked for some numbers)
6061 T6:
—UTS (Ultimate tensile stress) of 290MPa
—Yeild stress of 241MPa
General purpose aluminiums:
—UTS of ~117MPa
—Yeild stress of ~110MPa
So yeah…6061 T6 isn’t the aluminium you know and love.
But once again that relies on you getting the T8 result with home tempering without over inbrittlement. Most couldn’t but Derek with his armouring buddies and access to gear may be able to get that.
