hardness test

A hardness test measures a material's resistance to deformation, like scratching or indentation. It helps determine how tough or durable a material is, which is important for selecting the right material for specific applications. During the test, a specialized tool presses into the material under controlled conditions, and the size or depth of the resulting indentation indicates its hardness. Common methods include the Brinell, Rockwell, and Vickers tests, each suited for different materials and purposes. Overall, hardness testing provides valuable information about a material’s strength, wear resistance, and suitability for engineering or manufacturing use.
