Brass & Copper Electrical Components

Brass and copper are two foundational metals in the electrical industry, known for their exceptional electrical, thermal, and mechanical properties. These metals are used across a wide range of electrical applications—from wiring and grounding to terminals, connectors, and structural components. Each metal brings distinct advantages that make them indispensable in modern electrical systems.

Copper Electrical Components

Properties:

• Excellent Electrical Conductivity (~100% IACS)

• High Thermal Conductivity

• Ductility and Flexibility

• Good Corrosion Resistance

Common Components:

• Copper Wires and Cables: Primary conductors in residential, commercial, and industrial wiring.

• Copper Busbars: Used in high-current distribution panels, switchboards, and substations.

• Copper Lugs and Terminals: Provide strong and conductive connections for power and grounding.

• Earthing Rods and Braids: Essential for safe dissipation of fault currents.

• Copper Contact Tips: Used in circuit breakers, relays, and switches for high conductivity.

Brass Electrical Components

Properties:

• Moderate Conductivity (~28–40% IACS)

• High Strength and Hardness

• Corrosion and Wear Resistance

• Excellent Machinability

Common Components:

• Brass Terminal Blocks: Ideal for secure and corrosion-resistant wire connections.

• Brass Connectors and Sockets: Widely used in lighting, automotive, and communication systems.

• Brass Screws, Nuts, and Bolts: Mechanically secure electrical assemblies without compromising conductivity.

• Brass Cable Glands: Provide strain relief and environmental sealing for cable entries.

• Brass Pins and Plugs: Durable components in plug-and-socket systems, often nickel- or gold-plated.
