Tungsten

Chemical Formula: W
Atomic Number: 74
Atomic Weight: 183.84
Category: Transition Metal

Tungsten (also known as Wolfram) was first identified in the 18th century, but came to importance in during World War II due to its importance in the ammunitions industry. Today, tungsten concentrate is produced from wolframite (iron-manganese tungstate; FeWO4/MnWO4), scheelite (CaWO4), ferberite (FeWO4) and hubnerite (MnWO4). China produces 75% of the world’s tungsten concentrate, while Austria, Boliva, Portugal and Russia produce most of the remaining amount.
