Color Anodizing Shaft Stud

Anodizing is an electrolytic process, i.e. it uses an electrical current to generate an electrolysis reaction, which includes anodic oxidation and cathodic reduction. It is at this point that the aluminium anode is covered, almost entirely, by an alumina film.
It is during anodic oxidation that the thickness of the surface oxide layer increases. Its structure and characteristics can be modified according to the alteration of:
The nature of the electrolyte
Its composition
Its temperature
The treatment time

The voltage used

Products with anodized aluminum in:
Household appliances
Consumer electronics and technology
Sporting equipment
Electrical engines
The reason lies in the properties of the metal itself, such as its surface hardness, which makes it resistant to scratching, its thermal conductivity, the possibilities of colouring and, as we saw in the post about the aluminium composite panel, the possibility of aluminium being recycled in an unlimited way.
