Molybdenum is a silver-white metal with a high melting point and does not undergo oxidation reaction with air at room temperature. Because molybdenum has the advantages of high strength, high melting point, corrosion resistance, and wear resistance, it is widely used in steel, petroleum, chemical, electrical and electronic technology, medicine, and agriculture. Molybdenum wire is a common molybdenum product. In this article, we will take a look at the types and uses of molybdenum wire.
If molybdenum wire is classified according to the material, it can be divided into pure molybdenum wire, high-temperature molybdenum wire, sprayed molybdenum wire, and wire-cut molybdenum wire. Different types of molybdenum wire have different characteristics, and their uses are also different.
Pure molybdenum wire has high purity and its surface is black-gray. After alkaline washing, it becomes white molybdenum wire.
It has good electrical conductivity, so it is often used as a part of light bulbs. For example, it can be used to manufacture filament holders made of tungsten, lead wires for halogen bulbs, and electrodes for gas discharge lamps and tubes.
This type of wire is also used in aircraft windshields, where it acts as a heating element to provide defrosting function; it is also used to make electron tubes and power tube grids.
High-temperature molybdenum wire adds lanthanum rare earth element on the basis of pure molybdenum. This molybdenum-based alloy is more popular than pure molybdenum because it has a higher recrystallization temperature, is stronger and more ductile after exposure to high temperatures. In addition, after being heated to above its recrystallization temperature and processed, the alloy forms an interlocking grain structure to help resist sagging and structural stability.
Therefore, it is often used for high-temperature structural materials, such as printing pins, nuts and screws, halogen lamp holders, high-temperature furnace heating elements, and lead wires for quartz and high-temperature ceramic materials.
The sprayed molybdenum wire is mainly used for wear-prone automotive parts, such as piston rings, gearbox synchronization parts, gear selector forks, etc. A thin layer of coating is formed on the worn surface, which can make vehicles and parts subjected to high mechanical loads have excellent lubrication performance and wear resistance.
