Description
Cobalt is one of the most common metals in the world. It has a density of 8.9 g/cm³, a melting point of 1,495°C and a vapour pressure of 10-4 Torr at 1,200°C. It is a lustrous, hard, grey looking metal that is characteristically ferromagnetic. One of its most popular uses is as a blue pigment in paint, jewellery 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 manufacture of magnetic storage media and as a transition layer in the manufacture of batteries.

* This is a recommendation based on our experience with these materials in our sputter guns. Rates are based on non-bonded targets and are material specific. Bonded targets should be operated at lower power to avoid bonding failure. Bonded targets should be operated at 20 watts/square inch or less depending on the material.
