Don't know where you're at hulk, but Magnesium wheels are illegal to use in the USA. They banned them because they are EXTREMELY flammable. Be careful when curing.

Do you think the wheel will self cure if it spontaneously ignites? I guess that would be the time to have some extra items ready to be cured, because that oven would sure get hot

Looking around on the net, I found that magnesium melts at 650°C/1202°F.
One site says: The ignition temperature of massive magnesium is very close to its melting point of 650 degrees C (1,202 degrees F). (See Table 2.) However, ignition of magnesium in certain forms may occur at temperatures well below 650 degrees C (1,200 degrees F). For example, magnesium ribbons and shavings can be ignited under certain conditions at about 510 degrees C (950 degrees F), and finely divided magnesium powder can ignite below 482 degrees C (900 degrees F).

Has anyone powder coating ever had a problem with magnesium catching fire?

Come to think of it, it would be nice to pc my moms wheels. She's got a '66 MkII Sunbeam Tiger that has some awesome Halibrand mag wheels. Clear pc would sure protect them from the elements.

I've powdercoated some small scooter rims that were magnesium. They turned out good, but whenever other's want something magnesium done, I turn them down. It's not worth what could happen. In other words, I won't do magnesium again.

ShelbyCSXT,
I've done quite a few motorcycle parts marked magnesium with no problems. Check the album . My knowledge of magnesium fire hazards coincides with the info you posted. With 20+ years in a machine shop, I worked with one guy that his pevious employer no longer had a shop due to a magnesium fire. It was caused by someone not doing their job correctly and ignited a machine full of shavings. I haven't had any problems machining it. I don't have a problem with PCing it. I wouldn't advise putting it into a burnoff oven or trying to tig it. Magnesium fires are nasty with no doubt. This is my opinion from my own experiences. If someone has any doubts or hesitations, then they should not do it. Better safe than sorry.

Since when? You can buy Magnesium wheels right now... I think someone is blowing smoke up your behind.

And unless you are sanding the magnesium and there is a fine dust all over the place... I cant see them 'catching fire'.

I thought the only place mag rims were outlawed was on the drag strips.
