![]() ![]() ![]() The method for conducting a Brinell hardness test is defined fully in ASTM E10. What is Brinell Hardness?īrinell hardness is a scale used to provide a numerical value to the level of hardness of a material. Methods for evaluating hardness such as Brinell hardness and Rockwell hardness were invented in order to create a common understanding of hardness levels because of the variation of hardness among metals and even within a family of metals. Hardness levels can vary within a given type of metal depending on the alloying elements, heat treatment, work hardening, and other hardening methods used. Hardness is an important feature because the level of hardness that a metal has directly relates to its ability to resist wear. It is also defined as metal’s resistance to indentation, scratching, or abrasion. ![]() Hardness can be defined as the ability of a metal or metal alloy to resist plastic deformation, in a specific, localized location rather than in a general location. But how is the hardness of a metal alloy measured? This article goes in-depth on two of the most common types of hardness testing: Brinell hardness testing and Rockwell hardness testing. Tensile tests measure strength, impact tests measure toughness and bend tests measure ductility. There are many types of tests that have been created to measure the physical properties of metals. ![]()
