WebThe test is done by measuring the surface area of the indentation created by a diamond in the shape of a square-based pyramid. The HV number equals the force divided by the area (F/a). Carbide grades are usually in the range of 1,300-1,900 HV. Ceramics can reach a hardness of 2,000 HV, CBN up to 3,000 HV, and PCD up to 6,000 HV. WebShore hardness refers to the reading of the value measured by a Shore hardness tester. There are different Shore Hardness scales for measuring the hardness of different materials. There are five common types: shore A, shore B, shore C, shore D, shore 0, and shore 00. The Shore hardness conversion table listed below is for the convenience of ...
