Thank you Swall.
Do you by chance know if any mechanical properties change at all in 7075-O or is it completely stable in that condition?
Why is solution treated 7075-W use more often than 7075-O? O condition would be more ductile and easier to form am I correct?
I can't find any information on the natural aging time of 7075-O aluminum. I've checked the AMS book "Aluminum and Aluminum Alloys" and they dance around the question:
"Most of the heat treatable alloys exhibit age hardening at room temperature after quenching. The rate and extent of such...
