Molybdenum is an exceptional material. It is twice lighter per tungsten and has a high specific strength. Molybdenum wire is intensively used in light and heavy industries, as the metal is characterized by high heat resistance, refractoriness, and excellent ability to resist corrosion.
Most often Molybdenum wire has a diameter of 0.01-4 mm, as well as a smooth and even surface on which all kinds of defects are completely absent.It can be presented in various shades of gray: from almost black to silver.It is stored in a dry room, transported with extreme care. Molybdenum wire is widely used in radio engineering, electrical and a number of other industries, in particular, in the manufacture of vacuum devices, mirrors, light sources, heating elements of high-temperature furnaces, various medical equipment, thermocouples and much more.
According to the requirements for molybdenum wire, on its surface there should be no traces of oxidation, greases and other types of pollution. Molybdenum wire with a thickness of up to 0.4 mm is produced in dark gray or black, thicker sizes have a light gray tint. The surface of the molybdenum wire should be free of cracks and burrs, but requirements for thicknesses greater than 0.5 mm are less stringent, burrs that are true do not go beyond tolerances.
Molybdenum wire is highly resistant to the influence of the highest temperatures and mechanical damage, it is not prone to rust and can be located where there is the influence of hostile spheres, such as alkaline solutions, sulfuric, hydrochloric, hydrofluoric acids. It is the most reliable when compared with another metal wire. Molybdenum wire has a low rate of thermal expansion. According to a comparison with another known alloy - tungsten, molybdenum is the lightest, which provides enormous specific strength at temperature differences up to 1370 ° C. This alloy does not tend to oxidize under the influence of low temperatures. Alloys doped with molybdenum, as well as titanium, are ready to normally perceive heating up to such a temperature as 1500 ° C..
