Brinnel Hardness Testing

Hardness is a characteristic that applies to a range of materials—metals and nonmetals alike— and is defined as the resistance of the material to deformation. ASII experts measure hardness according to the requirements of the material and its applications with equipment calibrated to hardness scales, including

*  Mohs Hardness: Devised in 1812 and based on relative resistance to scratching, this test is now used mainly to identify minerals in the field.

*  Brinell Hardness: The oldest method still in common use, this instrument employs an indentor ball. Brinell hardness testing is frequently used to measure hardness of castings and forgings.
