What are Bimetallic Connectors?

Bimetallic connectors are electrical connectors composed of two different metals bonded together. Typically, these connectors consist of a copper or aluminum core and a layer of a different metal on the surface, such as aluminum, zinc, or tin. The core metal provides excellent conductivity, while the outer metal layer enhances the connector's mechanical strength and corrosion resistance. This unique construction enables Bimetallic Connectors to offer the best of both worlds regarding electrical and mechanical properties. Bimetallic connectors use the synergy of copper and a secondary metal to provide optimal conductivity and mechanical strength.

Properties of Bimetallic Connectors:

Electrical Conductivity:

In bimetallic connectors, the core metal, usually copper, ensures exceptional electrical conductivity. Copper is renowned for its low resistance, allowing for an efficient flow of electrical current through the connector. This property makes bimetallic connectors suitable for applications where high conductivity is critical.

Mechanical Strength:

The outer metal layer in bimetallic connectors provides enhanced mechanical strength and durability. The outer metal's choice depends on the application's specific requirements. Aluminum, zinc, and tin are commonly used due to their excellent mechanical properties, including resistance to bending, vibration, and thermal expansion.

Corrosion Resistance:

Bimetallic connectors offer improved corrosion resistance compared to connectors made of a single metal. The outer metal layer acts as a protective barrier, shielding the core metal from corrosive elements. This property ensures the longevity and reliability of the connectors, particularly in harsh environments or applications exposed to moisture and chemicals.
