Not sure where I fall on this one. I have some first hand industrial experience with anodizing on aluminum and magnesium. I am sure Harvey is well equipped to anodize aluminum. It is a well known process and not “proprietary” and commonly done. The market is huge.
Likewise for mag, but the market is much smaller so way fewer people do it - mostly only those serving critical aerospace applications. I seriously doubt that Harvey does anything close to a full blown Dow 7 conversion coat process, even less likely that he does Dow 17 anodizing. Both of these processes are environmental and regulatory nightmares. I would suspect that these wheels were not anodized even by Mahle - most likely conversion coated with one of the processes in Travi’s finishing link, primed and painted. For most of our uses, a mechanical finishing method (blasting or abrasive pad) followed by a zinc chromate primer and then epoxy painting would result in a very good service life in our “non-critical” applications. Doing a bit more research, if you insist on a conversion coating, here is a good one https://www.sanchem.com/magnesium-conversion-coatings.html. Not sure how available it is This is a non chrome bearing coating - chrome ones are highly regulated (bad carcinogens) PS - the chance of ever igniting a mag wheel in a paint cure oven is zero. |
