|Type of plating||Features (characteristic value)|
|Rhodium (Rh) plating||- For decorative use: Hv550 – 640
Preventing discoloration of silver plating.
- The corrosion resistance and oxidation resistance of rhodium are as good as it is insoluble in aqua regia (nitric acid:hydrochloric acid = 1:3).
- For industrial use: Hv800 – 1000
Utilized for contacts and switch members as the low contact resistance is small.
