Dark precious metal alloy with impressive properties

The new RHODUNA®-Alloy Black 1 is probably the only alloy to combine all the properties required of a dark precious metal surface. Abrasion resistance, an attractive price and, of course, a sophisticated and adjustable shade of black are surely the most important features.

Adjust the degree of blackness up to a deep black final layert

The degree of blackness is limited in the favor of color consistency and easy handling of the electrolyte. If a darker or completely black final result is desired, we have you covered. RHODUNA®-Alloy Black 1 is ideal as an interim coating for RHODUNA® 471 Black. This lets you adjust the degree of blackness up to a deep black final layer to meet your needs.

Jewelry, plug contacts, writing implements, bathroom fittings or even car interiors can now be given a finish in the black shade of your choice.

Cost savings of almost 50% compared to a pure rhodium electrolyte

Due to the 1:1 ratio of rhodium and ruthenium, the electrolyte is not just extremely easy to use but also provides financial benefits.

Ruthenium has almost always had a very stable and comparably low price. The price of rhodium, on the other hand, has almost quadrupled within two years. Thanks to the composition of the electrolyte, a saving of 45% or more is realistic compared with a pure rhodium electrolyte.
