A Guide to Silver Electroplating
Ever since the invention of coins and metal smithing, silver electroplating has been a popular metal finishing technique. The silver plating process has the most applications compared to any other types of plated metal. Silver electroplating is a popular finish in almost all industries. The effect it creates is unique and therefore difficult to substitute with any other metal. It is also the least expensive metal in comparison to gold and palladium, and has the following beneficial qualities:
- Highest electrical and thermal conductivity than any other metal
- Lift reflectance
- Low weight
- Low melting point
- Wear resistance
- High degree of lubricity
They are various types of silver electroplating, including bright silver, matte silver and semi bright silver.
What metals can undergo the silver plating process?
A silver coating is usually applied to brass, copper, white metal or nickel. It is also used to restore tarnished items such as cups, bowls, plates, cutlery and dishes, as it can considerably extend a product’s lifecycle.
What is the silver plating process?
The silver plating process involves a silver electroplating solution and electricity. Firstly, the object undergoes a rigorous cleaning process to rid it of any dirt and grime. It is then dipped into the solution and connected to the negative terminal of the power supply. The silver plating is then connected to the positive terminal so that the silver deposits onto the item. It is then submitted to the cleaning process again and dried.
What is silver electroplating used for?
A silver finish is mostly used to improve solderability as it hardens the surface and prevents corrosion. Often used in electronics, telecom and computer industries alongside:
- Bearings
- Shims and gaskets
- Electrical connectors
- Jewellery
- Automotive applications
- Dinnerware
