The hard material is a cpd. of at least one of the metals Ti, Zr, HF, V, Nb, Ta, Cr, Mo or W with at least carbon or oxygen or nitrogen. The binder comprises at least one of the metals Ti, Zr, HF, V, Nb, Ta, Cr, Mo or W. The material is shapable by e.g. extrusion to produce a non-porous body. Pref. the binder is 25-70% esp. 30-65% of the alloy by volume. Pref. the hard material is (Ti,W)C, TiC, Ti(C,N) and/or TiN and the binder is W. (Provisional Basic previously advised in week 8632) |
