Available in a range of 255 variations, our Rhodium disks offer you the benefits of Rhodium, which is a hard, silvery-white metal that’s highly reflective and resistant to corrosion. These disks are manufactured to tight tolerances and uniform thickness for applications that require precision parts, such as scientific instrumentation, electrodes, and reflectors for high-power lasers. With so many variations to choose from, we can provide Rhodium disks tailored to your specific application requirements.
