Products Description
Mo-La alloy is a high-performance molybdenum-based material strengthened with lanthanum oxide (La₂O₃) dispersions, combining molybdenum's ultra-high melting point (2610°C) with rare earth enhancement effects. The dispersed La₂O₃ significantly improves high-temperature strength (180MPa at 1600°C), electron emission performance (work function 2.8eV), and recrystallization temperature (1400-1600°C). Primarily used in advanced applications such as high-power microwave tubes, monocrystalline furnace components, and fusion reactor first walls, it can be processed into ultra-thin 0.05mm strips and exhibits superior weldability compared to conventional molybdenum alloys, making it a critical engineering material for extreme high-temperature and high-radiation environments.
Mola is also highly resistant to thermal shock and has a low coefficient of thermal expansion, making it ideal for use in high-temperature industrial applications such as furnace linings and heat exchangers. The lanthom Oxide provides a special microstructure that allows the alloy to be creep-resistant even under extreme use conditions. Mola Alloy is an ideal material for applications requiring dimensional stability and strength above the capabilities of Moly or TZM.
Features of Mo-La Alloy

Applications of Mo-La Alloy
Superconducting Applications: Mo-La alloy may be used in the development of superconducting materials for magnetic levitation trains, medical imaging equipment (like MRI machines), and particle accelerators.
High-Temperature Electronics: Mo-La Alloy could be used in electronic devices that operate at high temperatures, such as those found in aerospace or industrial settings.
Thermal Management: Its good thermal conductivity makes it suitable for use in thermal management systems where heat needs to be transferred efficiently.
Other Specialized Uses: Mo-La alloy may also be used in other specialized applications where its combination of properties is beneficial, such as in certain types of sensors or scientific instruments.
