An Aluminum alloy is an alloy primarily of pure aluminum, mixed with different alloying elements that give rise to an entire range of materials, each of which is designed to maximize a particular characteristic such as strength, ductility, formability, machinability, or electrical conductivity
This is the quality of metal that describes its ability to spring back after it is flexed - in effect, the stiffness. It doesnt have anything to do with how hard the metal is. Soft temper means that when it is bent, it stays bent, and it doesnt take much force to do it. Hard temper means that when it is bent, it springs back flat, and it takes a lot of force to put a kink into it. There are several degrees of temper; Soft, 1/4 Hard, 1/2 Hard, 3/4 Hard, and Hard. All metals are subject to temper, and it is a quality of the product that is imparted at the mill. It has no impact on hardness, color, machinability or weld ability. However, bending (kinking) and heating to a high temperature can remove the temper and soften the metal at that point. This is called annealing.
