In electrical connections using copper and aluminum conductors, bi-metallic lugs are extremely important. To create a secure and reliable connection, friction welding is used to fuse the aluminum barrel and copper palm of bi-metallic lugs. If there are no bi-metallic lugs between copper and aluminum, galvanic corrosion will occur, causing the connection to deteriorate over time and develop electrical resistance. Industries can reduce the risk of overheating and power outages by using bi-metallic lugs to provide long, reliable electrical connections.

Galvanic corrosion is felt when there are two various metals, such as copper and aluminum, making contact with each other under conditions of an electrolyte, say moisture or humid air. Upon contact, aluminum corrodes at a high speed, causing the conductivity to decrease and electrical risk. Bi-metallic lugs solve this challenge by offering a secure transition of the two metals, avoiding any direct contact and the possibility of corrosion. Also, proper utilization of the lugs improves conductivity, reduces the need for maintenance, and enhances system efficiency to the maximum level, hence a necessity in power distribution systems, industrial systems, and renewable systems.

For use in applications requiring secure electrical contacts, Pioneer Powers offers high-performance anti-galvanic corrosion and enhanced performance bi-metallic lugs. Their highly engineered lugs offer hardness, conductivity, and safety even in extreme conditions. Spending on bi-metallic lugs saves the life of electrical systems as well as maintenance costs, hence constituting a smart investment in modern electrical installations.
