Elettrozinco: treatments passivation of aluminium

The passivation of aluminium is a crucial process, thanks to which the treated product can reacquire its stainless characteristics. Passivation creates a protective film over the product surface.

Through our baths, the pickled and passivated aluminium is able to naturally restore its protective film, but it would require some treatments that would take too much time. Chemical passivation helps us to speed up the process.
