The high melting point of 2620 °C as well as its high-temperature strength allow the application of Mo at temperatures up to 1900 °C. Depending on its level of deformation, the recrystallization of molybdenum starts between 800 and 1200 °C. Between 1600 and 1800 °C a spontaneous grain growth takes place with a significant decrease in strength and hardness. Molybdenum and its alloys are mainly used because of their outstanding properties at high temperatures.

Advantages of Mo for high temperature applications:

• high melting-point
• low vapour pressure
• high hot-strength
• low thermal expansion
• low heat capacity
• high thermal conductivity
• high elastic modulus

Typical areas of application:

• spray wire for the automotive industry
• dimming shields for automotive lighting
• core- and support wires for the lighting technology
• electrodes for the melting of glass
• boats and coils for resistive evaporation
• sputtering targets for the coating technology
• semiconductor base plates for performance electronics
