Selecting niobium metal products
Technical searches for niobium metal, Nb metal and niobium alloys may refer to pure niobium, alloying additions or finished mill products. A purchase request should identify the required purity or alloy, governing specification, product form, dimensions, condition, testing, certificates, quantity and destination ZIP code. Suitability and availability are confirmed for the stated application.
Technical characteristics
Niobium (Nb) is the 41st element in the periodic table of D. I. Mendeleev. Its atomic weight is 93.986. This refractory, silvery grayish metal with a melting point of 2468 °C has a number of undeniable advantages. It is used in industry both as a pure metal and as an alloying component. For example, the alloy of niobium and silver is used to make collector coins (Austria). The undoubted advantages of the metal are:
- good machinability;
- corrosion resistance;
- excellent weldability;
- getter properties.

The supplier «Auremo» offers high quality products, complying with GOST and international standards.
Application
Refractory niobium and its alloys are indispensable for parts of aircraft and missiles, nuclear gas pedals, nuclear boiler shells (niobium carbide, melting temperature 3480 ° C), containers for molten metals and radioactive waste storage. Coolants in nuclear reactors (liquid potassium and sodium), move through niobium tubes. Niobium is in demand in the production of electrolytic capacitors; cathodes, anodes, grids of powerful generator lamps. Niobium alloys are used to make chemical equipment. It alloys chromium steels. It is also used in cryotrons — superconducting components of calculating machines.
