6.5 Aluminum Alloy Temper Designations. Information obtained from the MatWeb site:
6.5.1 Basic Designations.
6.5.1.1 `F' As Fabricated. No special control has been performed to the heat treatment
or strain hardening after the shaping process such as casting, hot working, or cold
working.
6.5.1.2 `O' Annealed. This is the lowest strength, highest ductility temper.
