Best of all worlds - .012 titanium and 1/8 fiberfrax. Hard to find,
but it's out there. Any alloy will do. Ti will burn, but it takes
something like 5000 degrees to light it, and you're not going to get
that in an engine fire. Commercially pure is the easiest to work
with. Try www.tigermetals.net, their prices are good, if they have a
piece big enough for you.
