One variety of this is measured by dropping a ball made of tungsten carbide on the surface in question; this is the indentation kind measured by the Brinell test, which is similar to the Rockwell test.
Steel alloy 1090 has the highest value of this quantity for any metal, and osmium has the highest value of it for any single element. One variety of this is measured by dropping a ball made of tungsten carbide on the surface in question; this is the indentation kind measured by the Brinell test, which is similar to the Rockwell test. One benchmark used for measuring another type of this property includes corundum and quartz as well as eight other minerals.
