Different
branches of industry become more and more in the coating of light
metals. Predominant are aluminum (density 2.8 g/mL) and
magnesium (density 1.8
g/mL). One reason for this is
to make the final products even more "light" without restriction of the
desired functionality.
Trailblazer is once
more the car industry but also telecommunication and electronics. As
magnesium is reactive in acid, in neutral and partially in an alkaline
environment, it requires a careful pretreatment as a prerequisite for
further coatings.
