Has anyone Powdercoated Magnesium?

[Heavykote]

I have some motorcycle parts to do that are magnesium. What are the characteristics of this metal?
I think it's a softer metal and therefore the outgassing process might breakdown the metal.
If anyone knows, what temp would be optimum for curing?

Be very very careful when working with magnesium. It is a flamable metal and will burn very hot!! I don't think that the temps needed to cure PC will make it burn, but if you are sanding or grinding it, the dust is easily ignited. I've heard of people getting badly burned from it. As for PCing it, Noob2PC PC'd a set of Cadillac magnesium valve covers. I believe that he had a lot of outgassing problems with it though. I'm sure he'll chime in as soon as he sees this. Good luck and be safe!!

I've done 2 magnesium engine parts off a Yamaha yz250f. I just pre-baked and coated as usual...no problems and the parts came out great.

I have powder coated a set valve covers that were mag.
I bought a black powder the was out gas free and it did work. It was used as a base coat under a mirror red. I did try one of the valve covers without this powder and it turned ugly as you know what from it out gassing so bad. So i do know this stuff does work at least 99% out gas free.

THINGIE!!!!!!!!!!!!! RUN!!!!!!!!!!!!!!!!!!!

Yeah a lot of Out Gassing, I prebaked at least 4 times and still got bubbles. If you look in the album for my pics you will see what they look like. At the Curing Temps there is no danger of fire. It is the Dust and particles from sanding that ignite first. be sure to sand in a very well ventalated area, if you have a fan use that to creat good airflow away from the part.

I know someone who did manage to light some on fire, he dropped it in a bucket of water and it flared up. It burns so hot it vaporizes the water around the peice and then uses the O2 from the water. You will have to use a Foam or Sand to put out a Mag fire. Kris, it was MTA.

Thanks for the answers to myquestions! I was planning on sandblasting it with either glass bead or coal slag. DO you thing that would be a problem?

I used Alum Oxide then finished up with a Drill powered wire wheel.

how do you tell the difference between magnesium and aluminum. Sometimes it looks the same. Thanks

OK, now I remember it being him. Didn't he get a bunch of dust on his shirt and burst into flames from a grinding spark? I vaugely remember the incident.
