hard is tungsten carbide? The hardness range of tungsten carbide is generally 86-94HRA, which is equivalent to 69-82HRC. Different types of tungsten carbide have different hardnesses. For example, cobalt-based alloys and aluminum-based alloys have higher hardness, generally between HRA82-94. The hardness of tungsten carbide can also maintain a high level at high temperatures. For example, at 900-1000\u00b0C, cemented carbide can still maintain high hardness and show excellent wear resistance. In addition, the hardness of wolfram carbide decreases with the change of temperature. For example, at 540\u00b0C, the hardness is 82-87HRA, and at 760\u00b0C, the hardness can still maintain 77-85HRA.
