Actually, I think that Monel is an alloy of nickel and copper, with
trace amounts of other stuff including iron.

Thanks, Bob K.

I just "googled" and found that there about a zillion Inconel alloys, but
that the primary constituents are Nickel and Chromiun with some others
including Iron and is primarily for high temperature applications.

Monel is promarily Nickel and Copper plus additional constituents and is
primarily for corrosion resistance.

Both were developments of the same company.

inconel being particularly suited to aircraft exhausts because it is
more resistant to erosion of the metal by the hot exhaust gasses.

if you arent going to use inconel at least use 316 stainless for its
non magnetic qualities.

aircraft compasses are actually useful at times.
