Jacob Brinell

Jacob Brinell was a Swedish engineer and inventor known for developing the Brinell hardness test in 1900. This test measures the hardness of materials like metals by pressing a hard steel or tungsten carbide ball into the surface under a specific load. The size of the indentation helps determine how resistant the material is to deformation. The Brinell method is useful for testing larger or rough surfaces and provides a reliable way to compare material hardness, making it valuable in quality control and material selection in engineering and manufacturing.
