Copper is a chemical element originated from the Old English name coper in turn derived from the Latin ‘Cyprium aes’, meaning a metal from Cyprus. It was early used in 9000 BC and discovered by people from the Middle East. “Cu” is the canonical chemical symbol of copper. Its atomic number in the periodic table of elements is 29 with location at Period 4 and Group 11, belonging to the d-block. The relative atomic mass of copper is 63.546(3) Dalton, the number in the brackets indicating the uncertainty.

Sputtering is a process whereby atoms are ejected from a solid target material due to the bombardment of the target by energetic particles. The extreme miniaturization of components in the semiconductor and electronics industry requires high purity sputtering targets for thin film deposition. The Cu sputter target is used for CD-ROM, decoration, semiconductor, display, LED and photovoltaic devices, functional coating as nicely as other optical information storage space industry, glass coating industry like car glass and architectural glass, optical communication, etc.
Our copper sputter targets are clearly tagged and labeled externally to ensure efficient identification and quality control. Great care is taken to avoid any damage which might be caused during storage or transportation.
SAM’s copper sputter targets are available in various forms, purities, sizes, and prices. All the sputtering target can be designed for customized uses. We also supply rare earth metals and most other advanced materials into rod, bar or plate form, as well as other machined shapes and through other processes. Get an inquiry right now.

I bought these for chemistry class to do some film coating experiments with. They function properly for what we use them for.
