metal hardness testing

Metal hardness testing measures how resistant a metal is to deformation, indentation, or scratching. It helps determine the material’s strength, durability, and suitability for specific applications. Typically, a small, standardized indenter presses into the metal surface with a set force, and the size or depth of the resulting indentation indicates hardness. Common methods include the Brinell, Rockwell, and Vickers tests, each using different indenters and testing procedures. These tests provide quick, reliable data to ensure metals meet quality standards and perform reliably under stress.
