Product Description
99.95% Purity Pure Tungsten Plate
1. Description Of 99.95% Purity Pure Tungsten Plate:
Tungsten plate is created and processed using powder metallurgy. The hot and cold rolled tungsten plate, sheet and strip products produced by rolling increase the crystallization temperature of tungsten by 500℃～700℃, which can meet the requirements of vacuum furnace operating temperature of 2500℃. Heat shield material needs.
Purity: >99.95%
Density: 19.3g/cm3
Flatness: ≤2%
Standard: ASTM B760

4.Application Of 99.95% Purity Pure Tungsten Plate:
After rolling and processing with deflection reaching 60% , the density of tungsten sheet basically comes close to tungsten’s theory density. Due to its high density and balanced internal structure, tungsten sheet possesses remarkable high creep strength temperature properties. High temperature resistance boats, titanium sputtering targets for plasma coating films, reflection shields, heating tape, connecting components for vacuum furnaces, cover plates for sapphire growth furnaces, and reflection shields are all common applications for tungsten sheet.
