Reply #1 - 01/17/11 at 10:40pm I think so, just be careful when welding around it, cause mag burns white hot, and easily ignites compared to other alloys. It also corrodes worse than aluminum We got a mag bell housing that weighs only 6 lbs, but only ran it a couple of times

YEP --- Mr. Carr is spot on. I don't even keep any Mag filler rod in the shop becuase it is freekin' of the hook price wise.

Bill -- You have one of the nicest, if not "THE", nicest car in the SS class. Concentrate a little more on driving, and a little less on saving a lb. or two............

A LOT of modern transfer cases for 4 wheel drives are being made out of magnesium so there must not be much of a strength problem. I"m not aware of any transmission cases, though, so what's your point?

I don't know what this question has to do with driving a car. I'm in the market for a Brinn and you can grab a used mag brinn or bert for the same cost as an Alumunum version.

All i can say is that i have run both the aluminum & mag transmissions, Bert & Brinn & both Bert & Brinn mag & aluminum bell housings. I repair & rebuild both & have Broken a lot of ears off of the aluminum transmissions & the aluminum Bert bell housings crack all over but i rarely see cracks in the mag stuff. I run all mag stuff now whenever i can with no problems. A lot of the issues are maintenance related & alignment problems. Tongue

i've seen mag burn and it burns WHITE HOT! but i was always under the assumption you had to get it super hot for it to ignite. i've seen it burned in the sand dunes near brawley and i think i was told its thrown into a hot camp fire to ignite it. not totally sure on that. but i'm not sure simple welding would ignite it.

it will burn in soild form, also in the buring stage with will react with water, true it must reach a high temp to ignite but is a real pain to but out once its in its combustion state. older VW block are mag, older wheel, and older parts. you don't really find to much on cars now days excpet for little pieces here and there.

Anything can ignite in powder form. It's a big threat in grain mills, or anywhere there is a large amount of airborn dust (powder).....

More than you might realize. The 2006 BMW 325i and 330i , uses an aluminium alloy insert for the cylinder walls and cooling jackets surrounded by a magnesium alloy, and a magnesium alloy is used in the 2006 Corvette Z06 engine cradle just to name a couple.
