Description
Mo La Alloy Electrode Rod is an alloy material composed of molybdenum (Mo) and lanthanum (La), commonly used in industrial scenarios with high temperature, high corrosion, or high mechanical stress. The following is key information about the material:
1. Material characteristics
✔High temperature performance: The melting point of molybdenum is as high as 2623 ° C, and the addition of lanthanum can enhance oxidation ✔resistance and high-temperature strength, making it suitable for working at extreme temperatures (such as arc welding and melting furnaces).
✔Conductivity: Molybdenum has good conductivity and is suitable as an electrode material.
✔Corrosion resistance: Lanthanum can form a dense oxide film, reducing high-temperature oxidation and corrosion.
✔Mechanical properties: Alloying can improve the brittleness of molybdenum, enhance its creep resistance and processing performance.
2. Main applications
🔹Arc welding/cutting: Used for welding or cutting electrodes of high melting point metals such as stainless steel and titanium alloys.
🔹High temperature furnace components: As heating elements or crucible supports, they are resistant to corrosion from molten metal.
🔹Electronic industry: Conductive components in semiconductor manufacturing equipment or electrodes in vacuum environments.
🔹Plasma spraying: used as an electrode material for surface coating processes.
3. Manufacturing process
✔Powder metallurgy: Molybdenum powder and lanthanum powder are mixed and pressed before sintering to ensure uniform composition.
✔Melting and processing: preparing alloys through arc melting or vacuum melting, followed by forging, rolling, or drawing into bars.
✔Surface treatment: Polishing or coating may be performed to enhance wear resistance/oxidation resistance.
4. Advantages and limitations
🔹Advantages:
Better high-temperature oxidation resistance than pure molybdenum.
Good conductivity and low thermal expansion coefficient.
Adapt to complex working conditions (such as high temperature+corrosive environment).
🔹Limitations:
Excessive lanthanum content may lead to increased costs.
Work hardening tendency requires control of the cold working process.
