Does anyone know?

Has anyone thrown any part of the China girl casing into a fire? I am curious as if these are a magnesium alloy or just aluminium?

yup magnesium cases , titanium pistons and rods , inconel 625 crank , all for $119

Just hold a Bic lighter against the case. If it sets your house on fire, it was magnesium.
No, they're aluminum, plain old cast aluminum, and not "pot metal" as I've seen some call it.

Jezus, so glad they're aluminum. Was spot welding a front motor mount to my frame with the motor attached to get the angle right and accidentally struck the case with my rod. Didn't even think to wonder if the cases were magnesium.

Didn't air cooled VW's have a magnesium block? I seem to remember my older brother telling stories about throwing them into a bondfire.

don't let the Ralf Nadier guy find out about the VW fire hazzard

Bug blocks are magnesium. I have seen them light up the whole darned desert for 15 seconds or so. 'Tis a sad ending for such a sturdy engine.

I don't know ,none of my old VW's did any bursting and the headlites were not that bright either

now I want to go hold a match under one and see what it does lol

Really, a propane torch will get the job done better.

Yes, the V-Dub cases were magnesium alloy, we just had to do some fancy welding on a 1/2 VW engine on an ultralight.
