  • What Are Refractory Metals?

    Although there are twelve refractory metals, only five are widely used: Tungsten, Molybdenum, Niobium, Tantalum and Rhenium. All but Rhenium have a body-centered cubic structure. Despite the fact that refractory metals have many similar qualities-such as high density, resistance to wear and corrosion-each metal is different in its own way, providing each with its own individual combination of qualities.
