I've read that when using diamond wheels to grind ferrous metals, at high temperatures the carbon in the diamond becomes soluble in the iron thus damaging the diamond wheel.
Is it okay to use a diamond wheel to grind a non-ferrous alloy like Tantung? Is there some similar solubility issue? It's an alloy that has:
- ~40% Cobalt
- ~30% Chromium
- ~15% Tungsten
- ~4% Carbon
- ~5% Nickel
- ~5% Iron
So it does have a small amount of iron in it but I am not sure how big an issue this is. Nor do I know if there are solubility issues with the other elements.
I ask because I have a diamond wheel and a CBN wheel, and although CBN wheel will work, it is was more expensive and generally more useful than the diamond wheel. The diamond wheel is harder and wears less, and does not get anywhere near as much use so I want to use it when I can.
