Old VW (i think) tranny cases were made out of magnesium. i hear stories of how my dad's generation would toss one in the fire, and the sonofabitch would go up like crazy, the fire pit was like staring at the sun supposedly.M.F.D.B. wrote:Much of the "aluminum" you come across is not pure. Especially in dirt bike parts. Aside from clutch covers and ocasionally stator covers, nothing is pure Magnesium, but an alloy of different percentages of Magnesium and Aluminum. Pure magnesium is lighter than Aluminum, but is very brittle and flammable. Manufactures put amounts of Mag into Aluminum to strengthin it, but like hardening steel, there is a point where hardening starts to actually become brittle.

Natural selection favors Smart people, so nature selects morons to be slow and dumb for tigers and stuff too eat. But in our modern world there just aren't enough tigers.

hell, at last years pismo trip we thre some kawasaki engine cases into the fire. Its not just for old guys 
The real irony of the old magnesium debate on the clutch cover is that it has the running dog looking emblem on the inside which was hondas logo for magnesium. But at the time I don't think anyone involved in the debate was aware of that
