    Cobalt (Co) Sputtering Targets


Cobalt is one of the most widely recognized metals in the world. It has a density of 8.9 g/cc, a melting point of 1,495°C, and a vapor pressure of 10-4 Torr at 1,200°C It is a lustrous, hard metal that is gray in appearance and characteristically ferromagnetic. One of its most popular uses is as a blue pigment found in paint, jewelry, and glass. It is often alloyed with other metals to make engine parts and cutting tools. Its two main vacuum applications are as a ferromagnetic layer in the production of magnetic storage media and as a transitional layer in battery fabrication.
