Molybdenum alloy Products

Main Characteristics:

- High melting point (2610°C)
- Low thermal expansion
- High thermal conductivity
- Low vapor pressure
- Excellent corrosion resistance against molten metals and glass

Mass Characteristics:

- Symbol: Mo
- Atomic Number: 42
- Atomic Weight: 95.94
- Density: 10.22 g/cc at 20°C
- Compressibility: 36 micron 2/N at 293°C

Chemical Properties:

- Molybdenum has extremely good resistance to corrosion by numerous acids, liquid metals and molten glass, provided oxidizing agents are not present. Molybdenum is relatively inert in hydrogen, ammonia, and nitrogen up to about 1100°C.

Mechanical Properties:

- Molybdenum distinguishes itself with those unique properties: high melting point, high creep resistance and low thermal expansion. The properties of the pure molybdenum could also be improved by alloying.
