Types and uses of molybdenum wire
Molybdenum is a silver-white metal with a high melting point and does not oxidize 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 industry, electronic and electrical technology, medicine, agriculture and other fields. Molybdenum wire is a common molybdenum product. In this article, we will take a look at the types and uses of molybdenum wire.
Types of molybdenum wire
If molybdenum wire is classified according to material, it can be divided into pure molybdenum wire, high temperature molybdenum wire, spray-coated molybdenum wire, and wire-cut molybdenum wire. Different types of molybdenum wire have different characteristics and their uses are also different.
Uses of molybdenum wire
Pure molybdenum wire has high purity and a black-gray surface. After alkali washing, it turns into white molybdenum wire.
It conducts electricity well and is often used as part of light bulbs. For example, it is used to make tungsten filament holders, leads for halogen bulbs, and electrodes for gas discharge lamps and tubes.
This type of wire is also used in aircraft windshields, acting as a heating element to provide a defrost function; it is also used in the manufacture of electron tubes and power tube grids.
High-temperature molybdenum wire is based on pure molybdenum and adds lanthanum rare earth element. This molybdenum-based alloy is preferred over pure molybdenum because it has a higher recrystallization temperature, is stronger, and is more ductile after exposure to high temperatures. Additionally, when heated above the recrystallization temperature and processed, the alloy develops an interlocking grain structure that contributes to sag resistance and structural stability.
Therefore, it is often used in high-temperature structural materials such as printed pins, nuts and screws, halogen lamp holders, high-temperature furnace heating elements, and leads in quartz and high-temperature ceramic materials.
Spray-coated molybdenum wire is mainly used for auto parts that are prone to wear, such as piston rings, gearbox synchronization parts, gear selector forks, etc. It forms a thin coating on the worn surface, which can make the vehicle and parts withstand higher stresses. wear and tear. It has excellent lubrication performance and wear resistance under mechanical load.
Molybdenum wire is used for wire EDM cutting of nearly all conductive materials, including metals such as steel, aluminum, brass, titanium, and other types of alloys and high-temperature alloys.
