FF-5131 Cyanide-free Copper Plating Chemicals for Fast Deposition Stable Process and Uniform Coating
FF-5131 Cyanide-Free Copper-Zinc Alloy Process / Copper Plating Chemicals
Product Features
- This process does not contain sodium (potassium) cyanide, lead, cadmium or other heavy metals
- Produces uniform, stable coatings with consistent brass appearance
- Excellent alignment suitable for both roll plating and rack plating
- Can be used for both surface coloring and thick brass plating (above 10μm)
- Primarily used in decoration, jewelry, handicrafts, and industrial applications
- Environmentally friendly alternative to precious metal cyanide plating
- 30% lower production and operating costs compared to sodium cyanide systems
Process Flow
Copper plating → Recycling → Rinsing → Activation (5~10% Sulphuric acid) → Rinsing → Plating of full bright nickel → Recycling → Rinsing → Activation (5% sulphuric acid) → Rinsing → Pure water rinsing → Electroplating cyanide-free copper-zinc alloy Gold → water washing → passivation → water washing → pure water washing → drying → spraying and baking.
