High Temperature Tungsten Plate Reflection Shields For Sapphire Growing Furnace
Tungsten plate is widely used in the construction of furnace tooling and parts and as a feed stock for the fabrication of parts for the electronics and semiconductor industries. Standard availability is described below. We can supply tungsten reflection shield / heat shields as per customers' requests.
We produce high quality Tungsten Sheet as one or our excellent and hot product. The thinnest tungsten Sheet we supply is only 0.05mm and the width of our tungsten Sheet is 610mm. The longest tungsten Sheet is 3,000mm. Our standard tungsten Sheet is 24" x 100" with thickness of .01" and .015".
Description of Tungsten Reflection Shields:
Purity: > 99.95%
Density: > 19.1g / cm3
Size: Made as per customers' designs
Working Temperature: 2000 C
Advantages of Tungsten Reflection Shields:
Melting point of 3410 °C
Excellent corrosion resistance
High dimensional stability
Outstanding creep resistance
Applications of Tungsten Heating Shielding:
As the heat-shield parts in the sapphire growth furnace, the most decisive function of tungsten reflection shield is to prevent and reflect the heat in the furnace. Heat-shield parts with high-density, exact-measurement, smooth-surface, convenient-assembly and reasonable-design has great significance in improving the crystal-pulling.
