1. Pure Molybdenum:

  • High melting point and high elastic modulus.
  • Low and resistor and vapor pressure.
  • Good heat resistance, thermal conductivity and thermal expansion coefficient.

2. TZM Alloy (Titanio-Zirconio-Molibdeno)

Compared with pure molybdenum, TZM alloy has following advantages:

  • Better heat resistance.
  • Higher recrystallization temperature.
  • Good creep resistance and weldability.

3. MHC Alloy (Molybdenum-Hafnium-Carbon)

MHC alloy has the following advantages which compared with TZM alloy :

  • Better creep resistance;
  • Higher heat resistance and recrystallization temperature.

4. MoLa Alloy (Molybdenum-Llanthanum)

MLa alloy compared with pure molybdenum has the following advantages:

  • Better creep resistance and welding performance;
  • Higher recrystallization temperature and higher thermal resistance.
  • Good plasticity after high temperature use.

5. MY Alloy (Molybdenum-Yttrium)

MY alloy compared with pure molybdenum has the following advantages:

  • Better oxidation resistance.
  • Higher recrystallization temperature.
  • Good weldability and molding.
  • Good adhesion with melted glass.

6. MW Alloy (Molybdenum-Tungsten)

MW alloy compared to pure molybdenum alloy has the following advantages:

  • Good resistance to molten metal corrosion interaction.
  • Higher recrystallization temperature and hardness.

7. MCu Alloy (Molybdenum-Copper)
