About hardness


Hardness is the property of a material enabling it to resist plastic deformation, usually by penetration of another object. The term “hardness” may also refer to stiffness, temper or resistance to bending, scratching, abrasion or cutting. In materials science there are three principal operational definitions of hardness:

  • Scratch hardness:

Resistance to fracture or plastic (permanent) deformation due to friction from a sharp object.

  • Indentation hardness:

Resistance to plastic (permanent) deformation due to a constant load from a sharp object.

  • Rebound hardness:

Height or speed of the bounce of an object dropped on the material, related to elasticity.

Measuring hardness


Hardness is not an intrinsic material property. There are no precise definitions in terms of fundamental units of mass, length and time. A hardness property value is the result of a defined measurement procedure.

The usual method to obtain a hardness value is to measure the depth or area of an indentation left by an indenter of a specific shape, with a specific force applied for a specific time. There are several principal standard test methods to express the relationship between hardness and the size of the impression or the rebound velocity on specific materials.

Vickers, Rockwell, Brinell and Leeb are the most common scales.

For practical and calibration reasons, each of these methods is divided into a range of scales, defined by a combination of applied load and indenter geometry or in case of the rebound method, by the weight of the impact body.
