The Environmental Choice is Clear

Since the early 1940’s, magnesium has been coated with hexavalent chromium based conversion or anodize coatings commonly called out in AMS-M-3171 (Dow1, Dow 7, Dow 9, Dow 17 , Dow 19 and Dow 20). The belief was that these chromate based coatings would provide superior protection against corrosion. However, the health risk associated with hexavalent chromium were unknown at the time these coatings were developed.

In the 1990’s, the Tagnite coating system was developed to provide excellent surface protection for magnesium without the use of chromates or other heavy metals in the electrolyte. In fact, no chromates or other heavy metals are used in any of the pre or post treatment solutions.
