Molybdenum alloy wire

Description
Fine wires made of molybdenum (Mo) and tungsten (W) for technical applications where specific refractory-metal properties are required. Standard stock diameters are available and custom diameters and surface finishes can be produced for volume orders and specialized uses.

Key product features

• Very fine wires down to 10 µm for precision applications
• Standard dimensions available from stock and custom sizes on request
• High surface quality and tight diameter tolerances
• Special doping and alloy variants to match application requirements
• Comprehensive final inspections and quality control procedures
• Large production capacity and flexible manufacturing processes

Typical applications

• Filaments and support/core wires for halogen, fluorescent and incandescent lamps
• Fine medical wire for devices and sensors
• Window and windshield heating elements (automotive)
• Coating systems, vacuum deposition targets and evaporation boats
• Satellite and aerospace components requiring refractory-metal parts

Materials and special grades

• Mo — molybdenum: creep-resistant, high stiffness, low thermal expansion, high thermal conductivity
• ML — molybdenum stabilized with ~0.3 wt% lanthanum oxide: increased creep resistance and higher recrystallization temperature
• Mo-ILQ — micro-doped molybdenum (~0.03 wt% La2O3): improved formability compared with ML
• W — tungsten: highest melting point among metals, creep-resistant, good electrical conductivity
• WVM — potassium-doped tungsten with stacked microstructure: improved dimensional stability at high temperature
• WRe05, WRe26 — tungsten-rhenium alloys: increased ductility, lower ductile-brittle transition temperature, improved creep properties

Technologies and processes

• Integrated production chain: powder production → pressing → sintering → hot working → wire drawing → finishing
• Automatic powder handling and process control to ensure material purity
• Hot working and process optimization specifically for wire manufacture
• Surface treatments: graphitizing, pickling, electropolishing
• Computer-controlled process management and eddy-current testing during production
• Comprehensive final inspections to verify specified properties
• Recycling and supply-chain integration for Mo and W powders
