Copper is now commonly used in electroplating, which involves applying a very thin coating of copper to other surfaces, typically metal or plastic, using electricity. Electroplating with copper is a commonly used process, mostly to protect other metals against corrosion. Because of its ability to provide a consistent and smooth covering, it is commonly utilized as an under-layer for additional electroplating. Before soldering, copper electroplating is frequently utilized, particularly in the electronics and aerospace sectors.
Types of Applications
One of the most important things to know about copper electroplating is that it is often used in the daily operations of many industries. It is used so frequently that most of us don’t even realize how different things would be without it. One of the most popular applications is radio frequency and electromagnetic interference. It works well with these two things because it is an excellent conductor.
Copper is often used as an underlay for nickel and silver plating because it improves their ability to bond to the surface. The medical industry utilizes copper because it’s resistant to all kinds of bacteria. Other applications include smoothing out imperfections in aluminum surfaces, coating pots and pans, improving the appearance of plastic and metal items, and more.
Limitations of Copper
While copper electroplating is used for many applications, it does have its limits. For example, it cannot be used with iron unless a nickel base coat is first applied because of how copper reacts with iron’s chemical properties. In some cases, a cyanide solution must be used with copper to help with adhesion.
