summarize

     1）High melting point

2）Very low vapour pressure (It is very important in the application of refractory and vacuum industry.）

3）Great physical strength in high temperature(used in structural members in a high temperature environment)

4）Anti-creep (high temperature load structure members). High dimensional stability. Such as forging die of large turbine blade in aeroengine.）

5）High modulus of elasticity  

6）Extremely low coefficient of thermal expansion (it is very important in application for metal ceramic structure

Such as in the field of LED, V-LED that is regarded as a future of high power LED will use molybdenum or molybdenum copper material as base material)

7）Excellent electric conductivity (metal property)

8）Excellent thermal conductivity (metal property)

9）Selective anti-erosion ability
