Products Description

Molybdenum wire mainly refers to a consumable material made of precious metals such as molybdenum that continuously moves with a high-voltage electric field during wire cutting processing to cut workpieces. The fine metal wire that continuously moves during wire cutting machine tool processing of workpieces is called electrode wire (also known as electrode), which can perform pulse spark discharge erosion on workpieces and cut metal shapes.

High-purity molybdenum wire is widely used in various fields due to its excellent high-temperature performance, mechanical strength, and electrical/thermal conductivity. It can be used for heating elements in high-temperature furnaces, filaments in electronic lighting, EDM (Electrical Discharge Machining) cutting, and coatings for automotive parts. Additionally, it is applied in aerospace and high-temperature industrial component manufacturing, demonstrating outstanding practicality and reliability.

Features

High melting point and low thermal expansion
Molybdenum wire has a very high melting point (2623°C) and a low thermal expansion coefficient (4.8 µm·m⁻¹·K⁻¹ at 25°C). This means it stays stable even in high-temperature environments.

Excellent thermal and electrical conductivity
Its thermal conductivity is 1.38 W/cm·K (at 298.2 K), and it has low electrical resistivity (5.2 µΩ·cm at 0°C). This allows it to efficiently conduct heat and electricity.

Good mechanical strength
Molybdenum wire is strong and flexible, and it maintains its mechanical properties even at high temperatures.

Strong corrosion resistance
It resists damage from many chemicals, especially in high-temperature conditions.

Applications

Heating elements for high-temperature furnaces
Because of its high melting point and good heat conductivity, molybdenum wire is often used in heating elements for industrial furnaces.

Electronics and lighting
Molybdenum wire is widely used in filaments, electron tube sockets, and halogen lamps due to its excellent electrical and thermal conductivity.

Electrical Discharge Machining (EDM)
EDM molybdenum wire is used for high-precision cutting of conductive materials, such as molds, turbine blades, and medical device components.

Coatings and welding
Coated molybdenum wire is applied in automotive parts like piston rings, synchronizer rings, and gearboxes for better wear resistance.

Aerospace and high-temperature industrial parts
Molybdenum alloy wires are used in aerospace and high-temperature industries because they offer improved strength and stability under extreme heat.
