Hardness Hardness H is the resistance of a mineral to scratching It is a property by which minerals may be described relative to a standard scale of 10 minerals known as the Mohs scale of hardnessThe degree of hardness is determined by observing the comparative ease or difficulty with which one mineral is scratched by another or by a steel tool
Up to a hardness value of about 300 HV the hardness value nuer given by the Vickers test is the same as that given by the brinell test Rockwell Hardness Test The Rockwell test differs from the Brinell and Vickers tests is not obtaining a value for the hardness in terms of an indentation but using the depth of indentation this depth being
