0.3mm Thick 99.95% Pure Polished Heat Shield Tungsten Foil Sheet Plate

Definition and characteristics Definition: Tungsten foil is a kind of metal foil with tungsten as the main component, usually through rolling and other processes to process tungsten into a certain thickness and width of the sheet.

- Characteristics: High melting point, melting point up to 3420ºC; High strength and hardness, can withstand greater external force and wear; High density, the density is about 19.3g/cm³; Good thermal and electrical conductivity, can quickly conduct heat and current; Excellent corrosion resistance, it is not easy to be corroded in a variety of harsh environments.

Production technology

Generally, high-quality tungsten powder is selected first, the billet is made through pressing, sintering and other processes, and then the billet is processed into the required thickness of tungsten foil through the rolling process. Rolling force, rolling speed, temperature and other parameters should be controlled during the rolling process to ensure the quality and performance of tungsten foil. In addition, subsequent processes such as annealing and surface treatment may also be included to improve the structure and surface quality of the tungsten foil.
