Borium is a generic name for tungsten carbide granules embedded in a matrix of softer metal. Borium® is a registered trademark of Stoody Deloro Stellite, Inc., for a "Metal Alloy of Exceeding Hardness and Used For Drilling, Boring, and the Like". 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.
