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. According to the application environments and the operating temperatures, TLWM offer the best molybdenum alloy for our customers.
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.
Parameter：
Provide all kinds of Molybdenum crucibles according to customer's drawings and machine to reach high precision.
