Molybdenum and molybdenum alloy properties and uses

 Molybdenum tube, the English name molybdenum. The density of 10.2 g of molybdenum  cc, melting point 2610 ℃, boiling point of 5560 ℃. . Molybdenum is a transition element, easily change their oxidation state, stable price +6.
  Molybdenum is mainly used for the steel industry, most of which is used directly after briquetting industrial molybdenum steel or cast iron, a small part before melting into molybdenum used in steelmaking. Molybdenum content in low alloy steel is not more than 1%, but the consumption accounts for about 50% of total consumption of molybdenum. Stainless steel, Molybdenum crucible is added, to improve the corrosion resistance of steel. Adding molybdenum in cast iron, iron can improve the strength and wear resistance. 18% of molybdenum, nickel-based super alloys have high melting point, low density and thermal expansion coefficient and other characteristics, used in the manufacture of various high-temperature aerospace components. Molybdenum in the tubes, transistors and rectifiers and other electronic devices are also widely used.
Molybdenum products have a wide application in industry. Pure molybdenum wire for high temperature furnace and wire cutting EDM there; molybdenum sheet used to manufacture radio equipment and X-ray equipment; molybdenum crucible for rare earth refining; molybdenum alloy head for seamless hot piercing plug; molybdenum and molybdenum alloy high-temperature ablation, mainly for heat flow orifice, bore artillery, rocket nozzle, tungsten bulb holder manufacture.
