Application areas of rare and refractory alloys

You are interested in the scope of rare and refractory metals? Supplier KMZ offers to buy at economical price and rare refractory metals. Supplier guaranteed timely delivery at any address specified by the consumer.

Technical characteristics

Rare and refractory metals are extremely resistant to heat and wear, they have an extremely high melting point. They have a strong affinity for oxygen and nitrogen at elevated temperatures and are highly resistant to corrosion at low temperatures. A leading place among the refractory metal is tungsten, molybdenum, tantalum and niobium. Rare metals include all rare — earth elements, and lanthanides. They are considered transition metals. In the geological deposits of these metals are contained in pure form and in the form of oxides. Because of the extreme high cost they are used as small additives to the alloys.

Tungsten

Tungsten — a gray metal with impurities is brittle, but in its pure form is very plastic and easy to handle. Of all known materials, tungsten has the highest melting point, lowest coefficient of thermal expansion and the maximum tensile strength. Application: electrical engineering, manufacturing balances, gyroscopes, tool alloys.

Molybdenum

Molybdenum is a silvery-white metal with a very high melting point and low coefficient of thermal expansion. Application: fabrication of the evaporation crucibles, electrodes, rocket engine, furnace components, tools for processing of glass and zinc, and electrical contacts.

Tantalum

Tantalum is a dark blue-gray metal with dense, very hard, brittle, with a very low electrical resistance. It is known for its corrosion resistance and has a high boiling point (3017 ° C). Application: production of capacitors, manufacture cell phones, DVD players, computers. It is also used for laboratory equipment and a substitute for platinum.

Niobium

Niobium is a soft, gray, ductile metal with properties very similar to tantalum. It becomes a superconductor at cryogenic temperatures. Niobium has a low density compared to other refractory metals and resistant to corrosion. Application: manufacturing of superconductors, alloying of steel, production of specialty glass and ceramics.

Choice

When selecting the semi-finished products of rare and refractory metals should be considered:

  • The outer diameter
  • Inner diameter
  • Length
