Bimetallic Terminals Can Eliminate Galvanic Corrosion Pathways In Humid And Hot Environments.

The use of bimetallic lugs price list in electrical systems often requires the fusion of different metal materials. In humid and hot environments, the electrochemical interactions between these dissimilar metals can form galvanic corrosion channels. This phenomenon is particularly pronounced at the metal interface where there is a significant equipotential difference between copper and aluminum. Electrolytes such as moisture and salt promote the formation of micro-cell effects, accelerating electron transfer between metals and leading to corrosion, oxidation at the interface, and performance degradation.

In response to this phenomenon, cable lug bimetal has implemented a systematic design in terms of material selection and interface treatment to mitigate the tendency of two conductors to form a corrosive cell under humid and hot conditions from an electrochemical perspective. bimetallic lugs By metallurgically bonding or mechanically transitioning the interfaces of two different metals, the contact layer between the conductors can have a controllable potential change curve, thereby balancing the driving force for the occurrence of galvanic reactions.

During the manufacturing stage of bi metal cable lug, copper and other materials such as aluminum are integrated through friction welding or transition alloying processes, adjusting the interface state at the microscale. This design can alter the electrochemical behavior between metals in complex environments such as humid and hot or salt spray conditions, suppressing corrosion propagation commonly seen in pure metal contact areas.
