Abstract

(Fe,Mn)WO4 – Mohs Hardness: 4 – 4½. Wolframite is an important ore of tungsten, and is named for its tungsten content, since wolfram means tungsten in German. It’s the main source of the metal tungsten, a strong and dense material with a high melting temperature used for electric filaments, armor-piercing ammunition, and tungsten-carbide machine tools. Tungsten’s use in the auto industry had primarily been in specialty areas, like studs for tires, and high performance parts in racing cars. China reportedly has the world’s largest supply of tungsten ore with about 60 percent.
