Niobium Suppliers

Niobium (or Columbium) is a chemical element with the symbol Nb (formerly Cb), and an atomic number of 41.

Niobium Properties and Appearance

Niobium is a light grey, crystalline, and ductile transition metal. The addition of Niobium produces a ductile metal with a hardness similar to titanium. Niobium has a soft gold luster and is part of the corrosion-resistant, high-temperature, and refractory alloy groups. Niobium is soft, ductile, and malleable and improves the performance of several metals when combined.

Niobium Applications
Due to its low density, Niobium is ideal in aircraft and chemical processing applications. It is hypoallergenic, making it useful in the medical and pharmaceutical industries. Niobium oxidizes very slowly and is used in jewelry as a hypoallergenic alternative to nickel. Niobium is also used in various superconducting alloys.

Other examples of Niobium applications are:

• Medical
• Welding
• Sputtering targets
• Nuclear
• Electronics
• Optics
• Jewelry

Vulcan Metal Group supplies Niobium in foil, sheet, strip, plate, rod, bar, wire, tube, pipe, ring and billet. Custom machined and finished parts supplied to print.

Niobium – Did You Know?

• It was named after a Greek goddess, Niobe, who was the Greek goddess of tears. Niobe was the daughter to King Tantalus, who inspired the naming of the element Tantalum. Niobium and Tantalum almost always occur side by side when in found.
• It was almost not discovered! John Winthrop discovered an ore in Massachusetts in 1734 and sent it to England. The mineral sat in the British Museum collection for years until it was analyzed in 1801 by Charles Hatchett. He discovered a new element in the ore and named it Columbium.
• The element was called columbium (symbol Cb) in the United States for about 100 years, while it was called niobium in Europe. In 1949, the International Union of Pure and Applied Chemistry compromised and officially adopted niobium as the element’s name.
• Nearly 80 percent of Niobium is used in the steel industry to create high-strength low-alloy steels. The use of Niobium in these alloys increases the steels’ mechanical and high-temperature strength, toughness, and corrosion resistance.
• According to the United States Geological Survey (USGS), nearly all niobium is mined in Brazil and Canada. The estimated amount of niobium in the Earth’s crust is thought to last for the next five centuries.
