The main uses of tungsten targets include:
1. Preparation of electronic devices: Tungsten targets are widely used in the preparation of electronic devices, such as integrated circuits (ICs), flat panel displays (FPDs), solar cells, etc. During the preparation process, the tungsten target is placed in a target gun in a vacuum chamber, and tungsten atoms or ions are released through ion bombardment or electron beams, which are deposited on the surface of the substrate to form the required tungsten film.
2. Conductive materials: Tungsten targets are often used in the preparation of conductive materials due to their good conductivity and high melting point. They can be used to prepare high-temperature resistors, electrode materials, high-power electronic devices, etc.
Users of tungsten targets include semiconductor manufacturers, display manufacturers, photovoltaic industry, electronic device manufacturers, scientific research institutions, etc. These industries and units widely use tungsten targets in the fields of film preparation, material research, and electronic device production.

Volframi sputterointi kohteita käytetään magnetroni sputterointi pinnoitteessa. Sputtering pinnoite on yksi tärkeimmistä fysikaalisen höyrylaskeuman menetelmistä (PVD). Sitä käytetään tallettamaan ohuita kalvoja, joilla on erityisiä toimintoja pinnalle. Sputtering kohteita käytetään pääasiassa litteän näytön pinnoituksessa, puolijohdepinnoituksessa
