The hardness range of cemented carbide varies according to different compositions and manufacturing processes. Generally speaking, the hardness range of cemented carbide is between HRA85~93, which is equivalent to HRC69~81.
Among them, tungsten carbide (WC) is a common carbide component in cemented carbide, and its hardness is very high, reaching more than 90HRA. At the same time, adding some other metal carbides, such as TiC, TaC, etc., to cemented carbide can also improve the hardness and wear resistance.
It should be noted that the hardness of cemented carbide is affected by many factors, such as composition, grain size, heat treatment, etc. Therefore, hardness and wear resistance will vary slightly in actual applications. At the same time, there are many hardness testing methods for cemented carbide, such as HRA, HRC and other scales, and the hardness values of different testing methods may also be different.
