Brinell hardness

Brinell hardness measures how resistant a material is to indentation, typically metals and alloys. It involves pressing a steel or tungsten carbide ball into the surface under a specified load. The size of the resulting indentation is measured, and the hardness number is calculated based on the load and the area of the indent. Higher Brinell hardness indicates a tougher, more resistant material. This test is useful for assessing the hardness of materials with uneven or rough surfaces, providing a standardized way to compare material strength and durability.
