Copper tube target is a high-purity copper material product used for vacuum sputtering coating. It belongs to a type of sputtering target material and is an important component in the vacuum coating industry. Copper tube targets are usually made of high-purity copper materials through a series of processing techniques, with specific sizes and shapes, such as flat copper targets and rotating copper targets. Flat copper target materials are usually in the form of sheets, such as circular, square, etc., while rotating copper target materials are in the form of tubes, which have higher utilization efficiency but are not easy to process and require multiple processing steps to be finally produced.
