ML is a molybdenum-based material doped with 0.3 weight% of La2O3 and is available as wire material. La2O3 particles in the nanometre range are responsible for a higher recystallization temperature compared to other conventional molybdenum materials.
Advantages compared to K-Si-Mo:
- higher recrystallization temperature
- elongated grain structure after recrystallization which leads to higher ductility after use at high temperatures
- better oxidation resistance
- higher stability of the welded joinings with Mo/MY
- higher creep resistance
Typical areas of application:
- core wires and conducting pins for the lighting industry
- heating elements for the high temperature furnace construction
MLR (Molybdenum-Lanthanumoxide-Recrystallized)
MLR is a molybdenum-based material which is doped with 0.7 weight% of La2O3. ML is available as semi-finished products like sheet and plate material. Stable fine-dispersed particles of La2O3 combined with elongated grain structure leads to very good high-temperature properties (especially creep properties) up to operation temperatures of 2000°C.
Advantages of MLR compared to pure Mo:
- higher stability against grain growth
- higher creep resistance
- better welding properties
Advantages of MLR compared to TZM for temp. >1400 °C:
- higher thermal stability
- higher creep resistance
- better ductility after use at high temperatures
Typical areas of application:
- heating elements or charge carriers for the high temperature furnace construction
- sintering boats
MLS (Molybdenum-Lanthanumoxide Stress-Free Annealed)
MLS is a Mo-material doped with 0.7 weight% of La2O3 and is available as sheet material in a stress-free relieved condition. The recrystallization leads to a fine-grained structure which is very stable for operational temperatures up to 1400°C.
Advantages of MLS compared to pure Mo:
- better ductility and suitability for high temperature applications
- better form durability (higher creep resistance) at temperatures up to 1400°C
Typical areas of application:
- boats and coils for resistive evaporation
- boats for powder reduction
- components for the high temperature furnace construction
