Rhodium is a rare, expensive metal that’s used to plate metals. It offers a reflective, shiny, and protective coat that hides imperfections and protects jewellery from scratches. Another benefit is it doesn’t tarnish, corrode, or require specific cleaning procedures.

Due to its qualities Rhodium can be used in circuits and other metal componnets to prevent corrosion and reduce the effects of high temperatures. It can also be plated onto to silver to prevent passivation. Specific applications include electrical contacts and aircraft spark plugs.

The common industry standard for Rhodium Plating are ASTM B634 and MIL-R-46085.
