Molybdenum (Mo) Wire | Pure Mo, EDM & Spray Wire

Heeger Materials supplies high-purity molybdenum wire for high-temperature furnace, electronic, EDM, electrode, heating, thermal-spray, and precision wire applications.

Available wire types include black molybdenum wire, cleaned molybdenum wire, EDM wire, spray wire, and custom wire. Standard diameter capability ranges from approximately 0.18 mm to 3.0 mm, with custom dimensions available according to material grade, surface condition, tolerance, and quantity.

Pure molybdenum is the primary material for general wire applications, while TZM and MoLa options can be reviewed for selected specialty requirements.

Molybdenum Wire Specifications

The molybdenum wire is produced by stretching high-purity molybdenum rods to various diameters, following pass rolling and rotary forging processes. Our wires offer several advantages, including excellent stability, tensile strength, precision cutting, and low elongation. HM offers a wide range of molybdenum wire diameters from 0.18mm to 3.0mm, with customizable options available upon request. Our factory produces 2,000 to 3,000 kg of pure molybdenum wire products every month.

*If the diameter is >0.125”, please check our Molybdenum Rod.

Molybdenum Wires Surface

•   Black Oxide - Surface is "as swaged" or "as drawn"; retaining a coating of processing lubricants and oxides. 
•   Cleaned - The surface is chemically cleaned to remove all lubricants and oxides. 

Molybdenum Spary Wire

Molybdenum spray wire and molybdenum wire share similar physical properties, both are made of molybdenum metal. However, molybdenum spray wire undergoes special surface treatment and structural optimization to meet the requirements of high-temperature melting, spraying, and coating adhesion in spraying processes, ensuring its effectiveness in coating applications. It can be applied in processes including Plasma spraying, Arc Spraying, Flame Spraying, HVOF Spraying, etc. If you require spraying applications, choose our high-quality Molybdenum Spray Wire.

Molybdenum Wire Applications

Molybdenum is an outstanding material that can meet the most exacting requirements of its high melting point, low coefficient of thermal expansion, and high level of thermal conductivity. 

• Molybdenum wire is used for profile cutting, H2 furnace, heater rod guide rod hook, mandrel, wire, lead, etc.
• Molybdenum is used in the manufacture of high-temperature-resistant equipment, such as brackets, guide rods, heating rods in the furnace, etc.
• Molybdenum wire is mainly used in molybdenum furnaces and electronic tube socket high-temperature hot fields. 

Molybdenum Wire Packing

Molybdenum wire is packed according to wire diameter, supply form, surface condition, and order quantity. Coils, spools, or bundled wire are protected against deformation, contamination, abrasion, and movement during transportation.

Export cartons, wooden cases, moisture-resistant wrapping, and custom packaging can be provided according to shipment requirements.
