How Does Hardness of Carbide Compare to Diamond?

Compared with the hardness of carbide and diamond, the hardness of diamond is higher.

Cemented carbide is an alloy material composed of metal carbides and bonding metals with high hardness, high melting point and high chemical stability, of which tungsten carbide is the most common carbide. Its hardness is generally between 1700-2000HV, and it has the characteristics of high hardness and high wear resistance. Therefore, it is widely used in industry to manufacture cutting tools, wear parts and structural materials.

Diamond is the hardest substance known in the world, with a hardness of up to 10, much higher than cemented carbide and other materials. Due to its ultra-high hardness, diamond is widely used in industry to manufacture cutting tools, wear parts and structural materials. It is also an important gemstone material.

Although the hardness of cemented carbide and diamond is quite different, they each have their own advantages and disadvantages in different application scenarios. Carbide has higher strength and corrosion resistance, and is relatively cheap, so it is widely used in some conventional cutting and wear applications; while diamond has higher hardness, wear resistance and thermal stability. Therefore, it is more popular in some application scenarios that require high efficiency, high precision and high wear resistance.
