Description
Iridium is a rare metal belonging to the platinum group of the periodic table. It has a melting point of 2,410°C, a density of 22.42 g/cm³ and a vapour pressure of 10-4 Torr at 2,380°C. It has a silvery white appearance and is highly resistant to corrosion. Its main application is as a hardener for platinum alloys, but it is also found in equipment used in high temperature environments.
It is evaporated under vacuum to produce particle and surface modification coatings, data storage devices and fuel cells.

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