Hardness is the ability of a material to resist being pressed into its surface by harder objects. The hardness test methods include the indentation method and the scoring method. According to the different test methods and the scope of application, the hardness units can be divided into Brinell hardness, Rockwell hardness, Vickers hardness, and Shore hardness. The different units are Different test methods, Which are suitable to the materials or occasions of different characteristics.
