4. Application of Molybdenum Circles For Semiconductor and Electric Vacuum Devices:
 
After rolling with a deformation amount of more than 60%, the density of molybdenum circle is basically close to the theoretical density of molybdenum, so it has high strength, uniform internal structure and excellent high temperature creep resistance, so it is widely used in production. Reflective screen and cover plate in sapphire crystal growth furnace, reflective screen, heating belt, connector in vacuum furnace, sputtering target for plasma coating, high temperature resistant boat and other products
 
Also molybdenum circle widely used as contact material in silicon controlled rectifier diodes, transistors and thyristors, mounting of power semiconductor devices and base materials for heat sinks,power semiconductor devices and electric vacuum devices.
