Keeping this in consideration, is there a way to harden aluminum?

6061-T4 aluminum is part way to the hardest that this aluminum alloy can be. The hardening process can be stopped by placing aluminum parts in a freezer until they're ready to be hit on the press again. After this secondary pressing, the parts go through an aging heat treatment process.

Additionally, what is the normalizing process? Normalizing involves heating a material to an elevated temperature and then allowing it to cool back to room temperature by exposing it to room temperature air after it is heated. This heating and slow cooling alters the microstructure of the metal which in turn reduces its hardness and increases its ductility.

Likewise, what does it mean to normalize metal?

Normalization is an annealing process applied to ferrous alloys to give the material a uniform fine-grained structure and to avoid excess softening in steel. It involves heating the steel to 20–50 °C above its upper critical point, soaking it for a short period at that temperature and then allowing it to cool in air.

What is the difference between full annealing and normalizing?

Annealing is a heat treatment process which alters the microstructure of a material to change its mechanical or electrical properties. The main difference between normalizing and annealing is that the cooling rate of normalizing is a little faster, so the production cycle of normalizing is shorter.
