Black Chrome (Smoky Chrome) Electrolyte BMG‑108.3
Decorative Black Chrome Plating Solution – Striking Dark Metallic Finish
Short Description
The Black Chrome (Smoky Chrome) Electrolyte BMG‑108.3 is a specialized electroplating solution for producing dark metallic black chrome coatings on metal surfaces.
This finish delivers a dramatic anthracite to deep black shimmer that is highly sought after for decorative and design‑oriented applications. It is a compelling alternative to black rhodium or black ruthenium plating and provides a distinctive, eye‑catching surface effect.
What is Black Chrome Plating Used For?
Black chrome plating is used when high contrast, dark metallic visual aesthetics are desired. Typical uses include:
-
Decorative finishes on automotive trim and accessories
-
Consumer electronics and luxury items
-
Jewelry and fashion hardware
-
High‑end metal components where a stylish black surface is preferred
-
Coatings over copper, nickel, gold or gold flash finishes
Compared with bright chrome, black chrome offers a unique visual style while still benefiting from chromium’s metallic properties.
How Does Black Chrome Plating Work? (Simple Explanation)
Black chrome plating is an electrolytic process in which chromium is deposited onto a prepared base layer (e.g., nickel, copper or gold) using direct current:
-
Surface preparation: The base metal must be clean, polished and thoroughly degreased.
-
Electroplating: The workpiece is connected as the cathode (negative pole). A suitable anode (such as graphite or platinum) is used as the positive pole.
-
Controlled plating: Under controlled voltage and temperature conditions, chromium ions are reduced and deposit as a dark, metallic black layer.
-
Finish: After plating, parts are rinsed and dried to reveal the final black chrome finish.
This plated layer combines decorative appeal with the corrosion resistance typical of chromium coatings.

Anode pad / tampon / anode sleeve / fuzzy sleeve / replacement fabric pad puffy from Betzmann Galvanik. This puffy fabric pad / anode sleeve or also called tampon is absolutely recommended for all plating processes. Optimally suitable for all coatings and electrolytes. The coating of larger areas is also quite fast with this pad. The insertion hole is larger than the electrode and therefore it happens that the moist anode pad slips off. Therefore, fix the pad on the electrode with a small rubber band.
