Tungsten sheets is 0.1mm thickness to keeep higher temperature strength property for LED Sapphire growing furnace application

Tungsten sheet, W sheet is very  for heating elements and radiation shields and working racks for LED Sapphire growing furnace

 

Applications

Tungsten has a unique property of which it's melting point can reach 3410 tungsten crucible is widely applied in high temperature vacuum furnace melting environment such as sapphire growing furnace, quartz glass melting furnace, and rare earth melting furnace. The working temperature of tungsten crucible is above 2000. For sapphire crystal growing furnace, high-purity, high-density, no crack tungsten crucible with other features of exact measurement and smooth surface has decisive influence on the success of crystal growth, quality control of pulling crystal, discharging and service life during sapphire growing process.

We can produce many varieties of tungsten and molybdenum parts for single crystal growing process with its best properties.
