Magnesium Parts

PostPost by: baileyman » Sun Jul 11, 2021 6:55 pm

I was looking in to how to treat my new mag cases and wheels since I was sure I would get trapped in the rain some time. My chemistry is poor, but I think I recall that there are ionic properties in soaps that are favorable for magnesium and especially in fabric softener. I thought at the time perhaps i would make up a sprayer with fabric softener in it and periodically spray things down. (Prolly would smell like a baby's butt!) Instead I have been using Boeshield, but it has not been adequately tested in local rains yet so I cannot report. I have found though that it will be good for me to go replace any stainless fittings touching mag cases to zinc, as the potential between them is lowered.

there are a number of PhD thesis written on the topic as to protect magnesium without the use of chrome, but if you are not overly concerned the Dow19 solution or similar (anodization with chromic acid) may be a way to stabilize the added lightness process.
