Silver Plating Additives

Precious metal silver in its pure state has a brilliant white metallic luster. It is a little harder than gold and has good electrical, thermal conductivity, malleability and solderability. It can be said that silver is an ideal material for plating. Silver plating involves placing the part in a vat containing an electrolyte, and an electric current enters the bath to promote the accumulation of silver onto the component. When the process is performed over nickel silver, the result is usually called electroplated nickel silver. Besides nickel silver, the process is also used on copper, steel, titanium, graphite, ceramic, plastic, and aluminum. In the silver plating process, we offer several common silver plating additives. For example, silver anti-tarnish agent, bright silver plating additive and silver sealer. These additives play an important role in the silver plating process, which mainly stems from the fact that they help to improve the properties of the plating.
