Chemical Chromating Of Magnesium - Chromate Free

Magnesium's highly active chemical behaviour and its liability to corrosion make it extremely important that it is adequately protected. Until now chromium based chemicals have been used to perform this protection medium.

We can offer a complete protection cycle that is FREE from any chromium containing compounds. "MAG-NON" is a completely new process that produces properties equal or better than chromium based solutions.

Major companies have found that MAG-NON meets or exceeds their specification in regards to bonding adhesion properties and corrosion resistance. Also it goes a long way in helping to achieve the new environmental regulations in regards to the reduction in the use of chromium compounds.

Set out below is comparisons of Magnesium alloys in salt spray tests.
