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.

WKL – Potassium Doped

WKL material is tungsten doped with ppm levels of potassium (K), aluminium (Al), silicon (Si) and is also produced principally as rod and wire. Compare with WKM, WKL wires have much longer longitudinal grain structure, which means much higher L/W value (grain length ratio grain width). According to produce processes, WKL wires find two main applications. One...
