Corrosion Management Of Bimetallic Terminals In Aluminum-copper Contact Environments
In electrical connections, direct contact between aluminum and copper can trigger electrochemical reactions, leading to a decline in contact performance. bimetallic lugs price Through material combination design, direct contact between aluminum and copper is isolated, extending the service life of the contact point.
Material Composition and Interface Characteristics
bimetallic lugs price list Typically, a transition layer process using both copper and aluminum is employed. The copper end is in close contact with the copper conductor, while the aluminum end connects to the aluminum conductor. The intermediate layer uses a compatible metal transition structure, maintaining conductivity while reducing electrochemical corrosion.
Interface Layer Design
-
Thickness Control: The transition layer thickness is uniform, ensuring mechanical strength and conductivity.
-
Surface Treatment: The terminal surface undergoes an anti-oxidation process to reduce the possibility of microscopic surface reactions.
-
Crimping Compatibility: The terminal design is compatible with different conductor specifications, ensuring uniform distribution of contact pressure.
Engineering Application Tips
In environments with high humidity or large temperature differences, the risk of corrosion at aluminum-copper contacts increases. cable lug bimetal Through material matching and structural design, a stable contact interface is provided. During use, attention should be paid to the terminal crimping tools and process standards to avoid localized loosening of the interface.
