Properties, History, Production and Uses of Boron

Although metallic boron has very few uses, the element is highly valued in a nuer of metallurgical appliions. By removing carbon and other impurities as it bonds to iron, a tiny amount of boron—only a few parts per million—added to steel can make it four times stronger than the average high-strength steel.
