Ahh but the question IS; can tungsten carbide tooling (since it is an
intimate "mixture" of tungsten, carbon, and cobalt), be correctly
referred to as metallic or a metal since the finished product has
metallic properties?
Neither one, Bob. It's a metal-matrix composite. Think about reinforced
epoxy. 'Same thing.
And so essentially is steel, which fairly uniformly is considered a
metal.
Now that everyone is awake .... a bit back someone was touting an
alloy of less than 50% Iron with no Carbon (IIRC) as a steel .....
X-750 nickel superalloy? SermaLoy 1515?
They were also claiming that jet engine turbne blades were made
of Chromium Steel .... G.
