Rare-earth and refractory metals
Rare earth or rare metals — a conventional group of elements, the benefits of which were appreciated only in the second half of the twentieth century. This is primarily due to the development of technology in the chemical and metallurgical industries. A similar situation is with refractory metals, the main area of application of which is represented by the space, aircraft building and nuclear industries. The supplier Auremo offers to buy products of high quality corresponding to GOST and international standards.
Heat-resistant elements — tungsten, molybdenum, vanadium, cobalt — are used as a component of hard heat-resistant alloys. Germanium is used in electronic, electro-vacuum technology. A whole range of modern industries depends on construction materials based on rare-earth elements. Instrumentation, machine building, metallurgy, chemical and nuclear industries have no equivalent alternative to products based on titanium, cobalt, molybdenum, tantalum, vanadium.
The name of the metal translates from German as wolfsbane. Tungsten is an element of the sixth group of the periodic table of D. Mendeleev. Atomic number — 74, atomic weight — 183.9, density at room temperature = 19.3 g/cm3. Refractoriness is 3395 + 15 degrees. Tungsten is the basis for heat-resistant alloys as well as the hardest steels (high-speed tool steels). It can be processed (forging, rolling, drawing) only by heating. Among the disadvantages of tungsten are its very high density, fragility at low temperatures and little resistance to oxidation at low temperatures. Heavy tungsten is used for balancing artillery shells, bullets and high-speed (up to 180,000 rpm) gyroscope rotors that stabilize the flight of ballistic missiles.
The refractory metal molybdenum is similar in properties to tungsten. Molybdenum has a melting point of over 2600 °C, a boiling point of over 4600 °C and a Brinell hardness of 125NV. Molybdenum imparts heat resistance, hardness, and wear resistance to elite tool steels. Molybdenum is indispensable for parts of electric vacuum devices and aircraft engines.
Vanadium is a coarse-grained, silver-colored material. It did not come into industrial use until recently. Vanadium is scattered in a variety of rocks and minerals, and its extraction and processing require modern technology. Nowadays alloys with vanadium are used in the production of steel and the metal is also added to titanium to improve the performance of the latter. Vanadium also serves as a catalyst in the production of sulfuric acid. In addition, the advances of modern science allow the use of vanadium in medicine, textile, glass and paint-and-varnish industry.
