Rhodium Coating
Rhodium coating for the medical technology, watch industry, precision mechanics and jewellery industry with the advantage of high hardness and abrasion resistance. Very high resistance to corrosion and chemical influences.
Overview of services:
- rhodium-plating of movement plates, hands, plates, balances for the watch industry of exclusive brands from Glashütte
- rhodium plating of jewellery
- rhodium plating of other small parts
- Electroplating of fine parts / small parts
The galvanic coating with the very valuable platinum by-metal rhodium has a high reflectivity and is also chemically and mechanically very robust. Rhodium also has high abrasion resistance and good resistance to corrosion in rhodium electroplating.

Rhodium coating by the galvanic process
The process of the galvanic coating with rhodium is called rhodinizing and belongs to the group of platinum metals. Platinum-rhodium alloys often serve as tarnish protection for silverware and are distinguished by their extremely hard surfaces.
