Product Name:

DS 555 Cyanide Free Copper Tin Alloy Process

Model No.:

DS 555

Classification:

Cyanide Free Alloy Plating Process

Feature:

 

1. Environmental-friendly process, don't contain cyanide, furthest eliminate the toxicity of electroplating, especially suitable for environmental friendly production, conform to european ROHS.

2. Fine plating, strong binding force, good dispersibility, widely applied to various kinds of complex components of plating in daily used hardware, light industry, machinery and instrument industry.

3. Good polishing performance for plating, low porosity,fine corrosion resistance, can be directly plated chrome or gun black, sand nickel, substituting chrome plating.

4. Plating solution is alkaline, no corrosive for equipment, also can be   as nitrogen impermeable plating, electroplating bearing and bearing alloy.

5. Easy operation for electrolyte solution, strong stability, easy to maintain that it's a kind of ideal new environmental -friendly process.
