Product Description
With extremely low saturated vapor pressure, low thermal expansion coefficient and extremely good high-temperature strength, tungsten and molybdenum materials are the best choice for high-temperature in-furnace heating elements.
Usually, we recommend that the operating temperature of heater is not more than 2,000℃and the operating temperature of tungsten heating bodies is not more than 2,800℃.
The recrystallization temperature of tungsten and molybdenum heater mixed with lanthanum, aluminum and potassium is obviously improved, thus improving the creep resistance and the oxidation resistance at the same time.
Application
Is widely used in production of sapphire crystal growth furnace reflective screen, cover board, reflective screen in a vacuum furnace, tropical, fittings, plasma deposition sputtering target material, high temperature resistant boat and other products.
