Specification

Our molybdenum wire is produced by stretching the Molybdenum rod to various diameter after the rod undergo the pass rolling and rotary forging to about 3mm. The Advantages of our molybdenum wire are good stability, good tensile strength, high precision cutting, and low elongation. Our factory can provide various of molybdenum wires with a diameter of 0.1~3.2mm, we can also provide custom products as per your requirements. We offer 2,000 to 3,000 kg of pure molybdenum wire products per month. Standard availability is described below. Other sizes and tolerances are available.

Molybdenum Wire Types	Diameter (inch)	Tolerance (%)
Molybdenum Wire for EDM	0.007" ~ 0.01"	±3% wt
Molybdenum Spray Wire	1/16" ~ 1/8"	±1% to 3% wt
Molybdenum Wire	0.002" ~ 0.08"	±3% wt

Applications

Molybdenum wire can withstand high temperatures and corrosion, it is used as heating material for high-temperature resistance furnaces, heating elements, automotive, aerospace, wire cutting machine;

With good electrical conductivity, molybdenum wire also can be applied to electronic tube sockets, stent filament incandescent lamp, halogen lamps, discharge tube sealing material, lead-wire, tungsten filament with the mandrel, the grid.

There are some other common uses for molybdenum wire such as cathode and spray material.
