Product Name: tungsten sheet & plate
1)Grade: W1,W2
2)Technical conditions: ASTMB760
3)Available Specification
Thkness: 0.2mm- 30mm Width:Max 550mm Length:Max1500mm
4) Usage: used in electronics, aviation, aerospace, electric light source, heating body in vacuum furnace, heat insulation screen, etc.
Note: the company adopts a proprietary production process. The hot and cold rolled tungsten plates, sheets and strips produced by rolling have increased the crystallization temperature of tungsten by 500 ℃ ~ 700 ℃.So the material could meet the requirement of heat shield materials with a temperature of 2500 ℃ for vacuum furnaces.
5)Surface : black, alkaline washing, polished.
6) Dimensional tolerance: (see the table below)
