Characteristics of the tungsten metal
1. The high melting point
2. Good thermal and electrical conductivity
3. Low vapor pressure at high temperatures
High purity tungsten sheets are widely used in the reflection shield, sapphire growth furnace, reflection shield, heating tape. Connecting pieces are applied in vacuum furnace. Tungsten sheets and disk are available with alkali washed or ground finish. The appearance of tungsten sheet is black or polished.
Tungsten sheets application
After rolling and processing with deflection reaching 60% , the density of tungsten sheet basically comes close to tungsten’s theory density. Therefore, tungsten sheet possesses the properties of high shield, heating tape, connecting pieces applied in vacuum furnace, titanium sputtering target applied in plasma coating film, and high temperature resistance boats.
