The Brinell scale measures indentation hardness by pressing a hard spherical indenter into a material under a known load. Proposed by Swedish engineer Johan August Brinell in 1900, it was the first widely adopted standardized hardness test in engineering and metallurgy.
Data available for 59 of 118 elements. Highest: Osmium (3920 MPa). Lowest: Cesium (0.14 MPa).
