Monel (varies by type of alloy--there are various types of monel) consists of roughly 67 percent nickel, 30 percent copper, and about a percent each of iron and manganese. So-called K-monel adds a bit of aluminum to the basic formula.

Back in the 40's and 50's, high-end water heaters were made with monel tanks. It's not terribly unusual to find them still in use today--monel has a remarkable resistance to corrosion. Yamaha's used monel for its piston valves.

Finke's been making carbon-fiber rotors for some time and the horn community seems to think that they're good stuff. It could be that the coefficients of expansion of the casing material and the rotor are pretty close.

Just like monel and brass, there are lots of different types of stainless steel. THe stuff used in Besson valves seems not to be particularly tough stuff.
