You are confused <G>.

And you opine is that Carbides are metals.
LOL ....

You don't seem to know, eh?

No "perhaps" about it, BB.
I think Wick got you yet again.

What part of "CARBIDE" was unclear?

WHY? Think you'll find either Carbides or Tungsten Carbide there?

Good for you. You can copy & paste stuff.
So can jb.

<sheesh>
NOW it's "Tungsten carbide tooling" .....
Rocks are opaque too so I suppose that you think that they are metals too ...
yet Sodium is soft ...

steel =~ Thermal Conductivity 51.9 W/m-K 360 BTU-in/hr-ft²-°F

Tungsten Carbide, WC =~ Thermal Conductivity 100 W/m-K 694 BTU-in/hr-ft²-°F
Natural Diamond =~ Thermal Conductivity 2000 W/m-K 13900 BTU-in/hr-ft²-°F

So Diamond is a metal too?

Nope.
