The decorative and electrolytic brass plating process has the aim to create deposits of polished, opaque brass, pearl on smooth or previously satined surfaces.
Bras plating has a mainly decorative purpose with obtainable thicknesses of about 0.025 microns carried over for the decoration up to even 6 microns certified according to the thickness requirements.
Thickness is normally used to obtain finishes with a sweeping or satin finishing effect or is used to be chemically bronzed.
The brass is obtained by electrodeposition using soluble brass anodes in copper, zinc, sodium cyanurate baths, plus other leveling, brightening (aluminum sulphate) and buffering substances. To obtain an adequate adherence of the brass layer on the piece to be coated, a substrate of some μ of nickel is preliminarily made.
The deposited brass layer is always protected with transparent or opaque varnish as needed.
The corrosion resistance of a decorative brass deposit depends exclusively on the protection given by the protective varnish.
The electroplated brass layer is not uniform in its distribution, in particular there will be areas such as edges or points where there will be a very marked deposition, while in the holes and in the undercut the deposition will be less.
We can coat the following materials after appropriate preparation treatments:
- Aluminum and its alloys after special preparation
- Carbon steels also heat treated
- Stainless steels
- Cast iron after sandblasting
- Copper and its alloys
The maximum dimensions of the parts that we can work are 1600x1100x300
