What are the Advantages of Using Aluminum and Copper Together in Bi-Metallic Lugs?

Bi-metallic lugs are concrete bases for any electrical system in which aluminum and copper conductors must be connected. These lugs are designed specifically to fend off galvanic corrosion, which initiates when direct contact of two different metals takes place. Being definitely bi-metallic, they create a firm, permanent, and effective medium of connection between two metals aluminum and copper.

Aluminum and copper metal lugs are mainly used to bridge the conductivity gap between the two metals. Copper has great electrical conductivity and is thus used in high-end applications, while aluminum offers worth of lightness and low price. After joining correctly by the bi-metallic lugs, both metals unite in sharing their thermal and electric properties without any possibility of corrosion or overheating. Typically welded by friction, such lugs deliver a secure and low-resistance joint. Due to their strong resistance to mechanical stresses and oxidation, bi-metallic lugs are found to be very suitable for industrial- and commercial-grade as well as utility electrical installations. Their design maintains low power losses and safety for extremely long durations. Bi-metallic lugs ensure the reliable linking of aluminum cables to copper busbars and terminals, be it for power distribution or control panels.
