    Cadmium Plating Alternatives and Coating Process

    Like cadmium, tin-zinc is also resistant against friction and wear. The bath for this process is a nearly neutral pH bath, making it relatively easy to dispose of without negatively affecting the surrounding environment. This cheap and relatively easy plating process has made tin-zinc plating all the more popular in recent years.
