is Hardness? Hardness is the measure of a material\u2019s resistance to permanent deformation, particularly indentation, scratching, or cutting. In practical terms, it describes how well a material can resist forces that attempt to dent, scratch, or wear it. Hardness is not a single absolute value; it varies based on the testing method used. Common hardness tests include: Vickers (HV) \u2013 uses a diamond pyramid indenter Rockwell (HRA) \u2013 common in cemented carbide rating Brinell (HB) \u2013 used for softer metals Mohs scale \u2013 qualitative scale from 1 (talc) to 10 (diamond) Tungsten carbide typically ranks extremely high on all these scales, often near 1500\u20132000 HV or 88\u201394 HRA.
