November 14, 2012

Q. I am trying to find an electroless system for coloring brass pins 3mm in diameter and from 4 mm to 10 mm long.

A. Hi John. Brass can be darkened to a brown-black color with liver of sulphur or proprietary brass darkening solution. But this may not offer the aesthetic, or variations, or conductivity , or wear resistance or corrosion resistance that you need. Brass can also be lacquered, and it is possible for the lacquer to include dyes to impart a tinted look. Electrophoretic lacquering is not electroless, but would give you a robust painted look with a very thin coating. Paint or powder coating is possible but good adhesion on brass requires a primer plus some hard work or good luck. Electroless nickel or electroless copper plating, or even immersion silver or immersion gold plating are possibilities.

Tell us your additional requirements as the next step please. Where are these pins used and what do they do? Thanks.
