We produce copper targets up to 99.9999% using smelting technology. Low gas content. The particle size distribution is uniform.

Copper target is one of the sputtering targets in the vacuum deposition industry. It is a product of high-purity copper materials after series processing, with specific size and shape. In particular, ultrahigh purity copper has many excellent characteristics and has been widely used in ion beam sputtering, Magnetron sputtering, etc. It can be plated with reflective film, conductive film, semiconductor film, capacitor film, decorative film, protective film, integrated circuit, display, etc,

The following pictures are two typical micrometallographic examination pictures of copper sputtering targets, with average particle size <50um.
