Technical Fact Sheet – Tungsten

2021-6-25  Tungsten is a naturally occurring element that exists in the form of minerals, but typically not as a pure metal (ATSDR 2005). The color of tungsten may range from white for the pure metal to steel - gray for the metal with impurities (NIOSH 2016). There are more than 20 known tungsten-bearing minerals (ATSDR 2005).
