• 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
