Molybdenum, the true "all-purpose metal". Filamlike products used in the lighting industry, semiconductor substrates for power electronics, glass melt electrodes, hot areas for high-temperature furnaces, and sputtering targets for flat-panel displays used to coat solar cells are ubiquitous in everyday life.
As one of the most valued industrial metals at present, molybdenum material has a very high melting point, even under very high pressure and temperature, will not soften or expand much. Due to these characteristics, molybdenum silk products are used in a wide range of applications, such as automotive and aircraft parts, electrical vacuum devices, light bulbs, heating elements and high-temperature furnaces, printer needles and other printer parts.
Molybdenum wire according to the material division, there are pure molybdenum wire, high temperature molybdenum wire, spraying molybdenum wire and wire cutting molybdenum wire. Different species have different characteristics and their uses are not the same.
Pure molybdenum wire has high purity, and its surface is black and gray. After alkali washing, it becomes white molybdenum wire. It conducts electricity well, so it is often used as part of light bulbs. For example, it can be used to make brackets for filaments made of tungsten, leads for halogen bulbs and electrodes for discharge lamps and tubes. This type of wire is also used in airplane windshields, where it acts as a heating element and provides defrosting; It is also used to manufacture valves and power tube gates.
The high temperature molybdenum wire is made of pure molybdenum with lanthanum and rare earth elements. This molybdenum-based alloy is preferred over pure molybdenum because it has a higher recrystallization temperature and is stronger and more ductile when exposed to high temperatures. In addition, after heating above its recrystallization temperature and processing, the interlocking grain structure of the alloy contributes to sag resistance and structural stability. Therefore, it is often used in high temperature structural materials such as printing pins, nuts and screws, halogen lamp holders, high temperature furnace heating elements and leads for quartz and high temperature ceramic materials.
Spraying molybdenum wire is mainly used in automotive parts that are easy to wear, such as piston rings, gearbox synchronizing parts, gear selector forks, etc. The formation of a thin layer of coating on the worn surface enables vehicles and parts under high mechanical loads to have excellent lubrication and wear resistance.
Molybdenum wire used for wire cutting can cut virtually all conductive materials, including metals such as steel, aluminum, brass, titanium, and other types of alloys and superalloys. Material hardness is not a factor in wedm.
