RHODUNA – Alloy Black 1
Dark precious metal alloy with impressive properties
Black rhodium is only of minimal interest to most mass producers due to the high price of the precious metal. Black ruthenium is only suitable for everyday objects due to its low abrasion resistance and slightly brown tone. RHODUNA-Alloy Black 1 combines both metals in equal parts into one electrolyte without the negative properties of either.
