Talking about Magnesium, I remember peeping a Ramchargers only 8-3/4 third member at the Nationals one time. It was a super cool piece of history and function. It was super light but I heard that they were not reliable past a certain amount of time, and that's with limited traction capabilities of the day. I think it was for their slingshot car.
IIRC, certain metals are due to burn, and burn brightly as in others will just liquidate/melt.
