Production Process and Product Quality Technical Standards:
Product application case:
Adding 6-30% TiC titanium carbide powder material to the tungsten carbide-cobalt cemented carbide can form a titanium carbide-tungsten carbide solid solution, which can improve the red hardness, wear resistance, oxidation resistance and corrosion resistance of the alloy. It is more suitable for processing steel than WC-Co cemented carbide. It is widely used in cemented carbide cutting tool products; it is applied to alloys such as Ni-Mo as binders to make tungsten-free hard alloys, which can improve the turning speed and the precision and smoothness of the workpieces. Used as an additive to make thermistors, improving their electrical conductivity and wear resistance.
