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.
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.
