Magnesium Anodic Treatment

[MIL-M-45202C]

Back | Home


Coatings range from thin clear to light-green, to thick dark green coatings. The clear coatings are used as a base for subsequent clear lacquers or paints to produce a final appearance similar to clear anodizing on aluminum. The light-green coatings are used in most applications which are to be painted. The thick, dark green coating offers the best combination of abrasion resistance, protective value and paint base characteristics.

The HAE anodic finish is probably the hardest coating available for magnesium. They exhibit stability at high temperatures and good dielectric strength. Excellent paint base. Requires resin seal or paint for maximum corrosion protection

Type I: Light coating.

Type II: Heavy coating.
