Molybdenum widely

Molybdenum crucible is an essential trace element the human body, animals and plants. The silvery white metal, hard and tough. Various human tissues are molybdenum, adult body total 9mg, liver and kidney of the highest concentrations. 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. Stainless steel, molybdenum is added, to improve the corrosion resistance of steel. Adding molybdenum in cast iron, iron can improve the strength and wear resistance. Pure molybdenum wire for high temperature furnace and wire cutting EDM there; molybdenum sheet used to manufacture radio equipment and X-ray equipment; molybdenum high temperature ablation, mainly for artillery bore, rocket nozzle, tungsten light bulbs manufactured stent . Plus molybdenum alloy steel can improve the elastic limit, corrosion resistance and to maintain permanent magnetism, molybdenum is required for plant growth and development in the seven kinds of micro-nutrients in one, without it, the plants can not survive. Animals and fish, and plants that also need to molybdenum. In other areas of molybdenum alloys and chemical fields of application are also expanding. Mo in thin-film solar and other coating industry, as the membrane surface of the substrate different have been widely used. Molybdenum matrix by adding other elements consisting of non-ferrous alloys. Major alloying elements are titanium, zirconium, hafnium, tungsten, and rare earth elements. Titanium, zirconium, hafnium, molybdenum alloy element not only from solid solution strengthening effect, maintaining low alloy ductility, but also form a stable carbide dispersed phase, increase the tensile strength and the recrystallization temperature. Molybdenum alloy has good heat conductivity, and low coefficient of expansion. Molybdenum alloy is the main way to strengthen the solid solution strengthening, precipitation strengthening and work hardening. Molybdenum in the twenty-first century is widely used in manufacturing weapons and equipment, modern high-precision and advanced equipment, the material requirements are higher, such as molybdenum and tungsten, chromium, vanadium alloys for the manufacture of ships, rockets, satellites alloy member and components.
