Molybdenum (Mo) and molybdenum alloy classification

1. Pure molybdenum (Mo)
The main properties of Molybdenum crucible are as follows:
? High melting point? Good thermal conductivity, thermal expansion coefficient is small? Resistance is small? Evaporating pressure is low? High modulus of elasticity? Excellent heat resistance
2. TZM (Ti - Zr - Mo) alloys
Than pure molybdenum TZM alloy has the following advantages:
? Heat better performance? Recrystallization temperature high? Creep resistance? Better welding performance
3. MHC (Mo - hafnium - carbon) alloy
MHC alloy TZM alloy compared with the following advantages:
? Heat resistance higher? Creep resistance and better? Higher recrystallization temperature
4. ML (Mo - lanthanum oxide) alloys
ML alloy compared with pure Molybdenum plate has the following advantages:
? Recrystallization temperature high? Creep resistance and better? Welding performance is good? High temperature after use good plasticity
5. MY (Mo - yttrium oxide) alloys
MY alloy compared with pure molybdenum has the following advantages:
? Recrystallization temperature? Antioxidant better? Welding performance? With glass sealing a better adhesion
6. MW (molybdenum - tungsten) alloy
MW compared to pure molybdenum alloy and has the following advantages:
? Has good resistance to molten metal corrosion? Higher recrystallization temperature? Higher strength
7. MCu (Mo - Cu) alloy
MCu alloy advantages:
? Has good thermal conductivity? Small thermal expansion
