    Personaly I would never put any type of fire to magnesium. Once it starts to burn look out /forums/images/graemlins/1zhelp.gif /forums/images/graemlins/1zhelp.gif Never ever put water on magnesium when it is burning either /forums/images/graemlins/eek.gif /forums/images/graemlins/1zhelp.gif /forums/images/graemlins/eek.gif We've looked in to turning some parts at work that are made out of magnesium, after about an hour of research, we put the blue prints in the trash /forums/images/graemlins/deal.gif Good luck

    Magnesium burns white hot when ignited and you can't put it out with hardly anything. I wouldn't get anywhere near it with a plasma cutter. /forums/images/graemlins/eek.gif

    magnesium is COOL when it burns. If it starts going out poor some water on it and itll come back to life. Really neat stuff in small amounts

    if you do it, call the FD first, set up a LOT of video cameras, and dont do it near your house!!

    bandsaw or similar ONLY. mag starts and there is only a few ways to put it out. sand works well, but it just encapsulates itself in the newly formed glass. a few other high dollar things out there do it as well. but they are glorified sand.
    good luck, and like i said, if you do do it then i want a video of it.

    if you cut it withanything have something with witch to put it out. sand will work but make sure it is dry dry dry dry. water ill make it explode, if you can find an extinguisher or sand like stuff it must be rated for a class D fire the d will have a star around it. try a meachen shop they might have some if the work with, magnesium, or alumanium /forums/images/graemlins/angryfire.gif1 be carefull, with the saw so as not to heat it up and don't use plasma enuff heat and it will take off on you.

    Isn't magnesium really hard to start on fire? I know that once it starts it won't stop, and I wouldn't take a chance with the plasma cutter, but isn't it damn near impossible to get it going?
