RHODUNA®-Alloy 1 Technical Rhodium-Ruthenium-Electrolyte

Meets the new requirements for wearables and mobile phones

Ease of use, attractive design and strong performance have always been the main arguments for buying wearables and mobile phones. But more and more important are the small differences such as a long lifetime and compatibility with fast chargers.

These expectations cannot be fulfilled with gold-plated charging contacts & connectors (USB-C, Pogo Pin, etc.). Gold-plated contacts corrode during the charging process if they have been in contact with salt water, swimming pool water, sweat or beverages, which leads to numerous complaints and the costly replacement of damaged devices.

If the contacts are coated with RHODUNA®-Alloy 1, they are protected against corrosion. This does not affect the ability of the devices to charge quickly. RHODUNA®-Alloy 1 has been used since 2016 for electronic contacts in reel-to-reel equipment as well as in barrel and rack operation in series production.
