Molybdenum wire is a common molybdenum product. If classified by material, it can be divided into pure, high temperature, sprayed and wire-cut molybdenum wire. Different classifications also create different characteristics and uses.

Molybdenum is a silver-white metal with a high melting point and does not react 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.

The purity of pure molybdenum wire is very high, and its surface is dark gray. After alkaline washing, the surface is white. It has good electrical conductivity, so it is often used as part of a light bulb. For example, it can be used to make 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; it is also used in the manufacture of electronic tubes and power pipe networks.

High temperature molybdenum wire is added with lanthanide rare earth elements on the basis of pure molybdenum. This molybdenum-based alloy is preferred over pure molybdenum because of its higher recrystallization temperature, higher strength and better ductility after exposure to high temperatures. Additionally, after being heated above its recrystallization temperature and processed, the alloy develops an interlocking grain structure that helps resist sag and is structurally stable.

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 lead wire for quartz and high temperature ceramic materials.

Sprayed molybdenum wire is mainly used for wear-resistant auto parts, such as piston rings, gearbox synchronization parts, gear selector forks, etc. The formation of a thin coating on the wear surface can give vehicles and parts subject to high mechanical loads excellent lubricity and wear resistance.

When molybdenum wire is used for wire cutting, it can cut almost all conductive materials, including metals such as steel, aluminum, brass, titanium, and other types of alloys and superalloys.
