摘要:
Cemented carbide material consists essentially of 70 to 90% by weight of tungsten carbide or of a mixture of tungsten and carbide at least one transition metal carbide, the transition metal being one other than tungsten selected from Groups IV to VI of the Periodic Table and 10 to 30% by weight of a binder. The binder contains 20 to 90% by weight of nickel, 10 to 80% by weight of cobalt and 5 to 25% by weight of chromium as the base ingredients thereof. The cemented carbide material has improved resistance to oxidation, to wear and especially to thermal cracking and is therefore suitable for rolls, guide rollers and dies for plastic hot working.
