Borium
Borium is a product that consists of tungsten carbide granules embedded in a matrix of softer metal. Borium is used in farriery to improve traction for horses. Other applications include ploughshares, saw teeth, cane knives and drill bits. Borium should not be confused with the chemical elements barium, bohrium or boron, the last of which is called borium in a number of languages.
