Best process to achieve antique brass finish

Hello Community, I’m looking for a finish that closely resembles antique brass—rich, aged tones with some depth and texture, for aluminum parts for a decorative lighting fixture. I’m not sure which method (Electroplating or powder coating with metallic effect?) would achieve the most authentic look while ensuring durability for indoor use. Any tips on surface prep, finishing processes, or suppliers who specialize in this type of work?

The cheapest option would be to anodize and then dye with a brass-colored die. The obvious disadvantage is that the characteristic aged look for brass cannot be achieved as the brass anodizing won’t react with the to produce the depth and texture that you are looking for. You can also use specialized paints.

      The most authentic finish would be brass electroplating. However, this is a complex process requiring pre-treatments like degreasing, zincating, nickel plating, and then brass plating. This is not something that can be done at home by an amateur, but any company doing electroplating will be able to assist.

        Once I have plated brass, how do I age it?

        There are a number of methods. The simplest is to use a vinegar and salt solution that is typically brushed onto the part. There are also commercial spray and brush-on solutions that will be more effective at patinating the brass to give it the characteristic patina. Don’t forget to paint the part with a clear lacquer to ensure the finish does not change over time.
