annealing alluminum
annealing alluminum
(OP)
hello everyone,
First i would like to apolozize for my ignorance, i am a plastics guy. At my company we etch .062 alluminum sheet on one side. Removing material from one side causes the sheet to bow and roll.
I was wondering what would happen if i clamped the sheet flat and annealed it. I was wondering if anyone had any comments as far as temperature and time. Also if they think this will work.
Thannks for your time

For 1xxx, 3xxx, and 5xxx series Al alloys, the chemical composition is such that they do not respond to the above treatments (no increase in strength). They are only strengthened by strain hardening (cold working).
What is the specific alloy that you are processing? The time and temperature will depend on the alloy and its prior thermomechanical processing.

My next question is should the stress relieving be done before or after etching? I will be testing both.

The advantage would be avoiding annealing.
You could also start from annealed sheets, but then why selecting 2024? Other materials would provide the same strength of 2024-O.
