Molybdenum-Tungsten Alloy

Mo-W alloys are widely used in demanding environments where materials must withstand extreme heat, corrosion, and mechanical stress.

Classification:


  • Molybdenum-Tungsten alloy, commonly abbreviated as Mo-W alloy, is a solid solution alloy composed primarily of molybdenum (Mo) and tungsten (W). The tungsten content typically ranges from 5% to 50%, depending on the specific grade and intended application.

    This alloy combines the advantageous properties of both molybdenum and tungsten, offering exceptional strength, hardness, and excellent resistance to high temperatures and corrosion. The addition of tungsten enhances the alloy’s melting point, density, and high-temperature performance, while maintaining good machinability and ductility provided by molybdenum.

    Key Properties:

    • Extremely high melting point (higher than pure molybdenum)
    • Excellent high-temperature strength and stability
    • Superior resistance to corrosion and erosion in harsh environments
    • Good electrical and thermal conductivity
    • High density and hardness

    Typical Applications:

    • High-temperature furnace components (heating elements, shielding)
    • Aerospace and defense industries (missile and rocket nozzles)
    • Electronics (cathodes, anodes, and X-ray tube components)
    • Nuclear industry (radiation shielding, structural components)
    • Sputtering targets for thin film deposition
