Niobium
Niobium, formerly known as columbium, is a stone element with the symbol Nb and atomic number 41. Niobium is a light grey, crystalline, and ductile transition metal. Pure niobium has a hardness similar to that of pure titanium, and it has similar ductility to iron. Niobium oxidizes in the e…
Molybdenum
Molybdenum is a stone element with the symbol Mo and atomic number 42. The name is from Neo-Latin molybdaenum, from Ancient Greek Μόλυβδος molybdos, meaning lead, since its ores were confused with lead ores. Molybdenum minerals have been known throughout history, b…
Tantalum
Tantalum is a stone element with the symbol Ta and atomic number 73. Previously known as tantalium, its name comes from Tantalus, a villain from Greek mythology. Tantalum is a rare, hard, blue-gray, lustrous transition metal that is highly corrosion-resistant. It is part of the refractory met…
Learn About Refractory Metals - The Balance
Dec 10, 2018 · Learn About Refractory Metals ... Widia, the first commercially available tungsten carbide, was developed by Osram Company (Germany) and marketed in 1926. This led to further testing with similarly hard and wear resistant metals, ultimately leading to the development of modern sintered carbides.

Tungsten Tubing - Tube Hollows International
Tungsten is a very dense material, almost as dense as gold, and 50 percent more dense than lead. However, this refractory metal is far more environmentally friendly than lead and less expensive than gold. Tungsten’s density makes it an ideal radiation shielding material for use in medical devices (e.g. radiotherapy devices).
