Chromium Sputtering Target

We offer Chromium Sputtering Targets in a range of 16 options, with diameters from 25-150mm and thicknesses from 3-6mm. Chromium has high hardness, strength and corrosion resistance. Properties that make these discs useful for sputtering applications like thin film coatings for wear resistance. The variety of diameters and thicknesses we offer means that Chromium Sputtering Discs can be used across different deposition systems and coating requirements.
