Silver Plating




Electrolurgy’s Industrial silver plating is an excellent corrosion resistant coating that can be plated on steel, aluminum, copper, bronze and stainless steel alloys. Because of silver’s conductivity and excellent solderability, it is often plated onto electrical components. It is widely used in the aerospace industry on engine turbine components for its outstanding lubricity, even at high temperatures. For the same reason, it is sometimes used as a break-in coating on gears. Electrolurgy offers silver plating for non-decorative industrial applications which are typically dull, matte or semi-bright in appearance.

Unique Properties of Silver:

Highest Electrical & Heat Conductivity
Silver has the highest electrical and heat conductivity and the lowest contact resistance of any metal, making it ideal for the electronics industry. It is often chosen as a less-expensive alternative to gold for electrical connections.

Toxic To Bacteria & Other Micro-Organisms
Silver has found extensive use in the communication and medical industries. Silver is toxic to many bacteria and other micro-organisms, which makes it perfect for use in many home water filtration systems.

About Silver Plating Baths
The majority of all silver plating is performed using an alkaline cyanide solution. Silver Plating baths can be modified so that the silver deposit ranges from matte to bright as deposited. Unless appearance is an issue, matte silver deposits are preferred. They are less brittle and solder better than do bright deposits.

About Silver Tarnish & Silver Sulfide
Silver tarnish is not an oxide; silver oxide does not form easily. When silver reacts with hydrogen sulfide, silver sulfide (tarnish) is produced. Silver Sulfide is not conductive or solderable. Often a secondary treatment is applied after plating which inhibits the formation of Silver Sulfide, allowing for easier soldering of the part.
