Dull Nickel Plating is a type of electroplating process where a layer of nickel is deposited onto a metal surface, resulting in a matte or non-reflective finish. Unlike bright nickel plating, which produces a shiny, mirror-like surface, dull nickel plating offers a more subdued, satin-like finish. This process is commonly used for its functional benefits, such as corrosion resistance, wear resistance, and its aesthetic appeal where a less glossy appearance is preferred.
