Power Systems

Used in cable conductors, busbars, and similar applications, it reduces wiring burden and material costs while meeting high current carrying demands.

Telecommunication Equipment

Commonly used in coaxial cables, signal connection wires, and similar structures, the copper layer ensures stable high-frequency transmission, while the aluminum core effectively reduces system weight.

New Energy Vehicles

Used for battery tabs and conductive rails, such as copper clad aluminum wire for automotive, meeting the dual demands of lightweight design and reliable conductivity.

HVAC & Heat Exchange

Copper-aluminum composite tubes offer excellent thermal conductivity, making them suitable for air conditioning condenser systems, heat dissipation modules, and more.

Consumer Electronics

Used in flexible circuit boards, connectors, and other precision electronic components, achieving the perfect integration of conductivity and mechanical performance.

Lithium Battery Manufacturing

Used as current collectors, such as copper clad aluminum battery cable, providing stable connections for power batteries and improving energy conversion efficiency.

Copper Clad Aluminum Manufacturing Processes

Roll bonding

Suitable for continuous products such as strips, busbars, and foils, copper and aluminum are firmly bonded under high temperature and pressure, ensuring a uniform and dense bonding surface, ideal for large-scale, high-efficiency production.

Explosive welding

Uses explosive shock waves to create instant high pressure, achieving molecular-level bonding between copper and aluminum.

This process provides extremely high bonding strength and is widely used for thick plates, structural components, and applications requiring high reliability.

Diffusion bonding

Involves high temperature and pressure in a vacuum or inert atmosphere to allow copper and aluminum atoms to interdiffuse.

This results in a clean interface, making it ideal for industries with high corrosion resistance and long-term stability requirements (such as new energy and battery connections).

Co-extrusion

Copper and aluminum cores are simultaneously extruded through a mold, ideal for producing copper-clad aluminum wire and busbars, offering dense bonding and high extrusion efficiency.

Copper-Aluminum composite processing guide

Cutting

Saw cutting is recommended with fine-tooth blades and proper cooling. For punch cutting, use flat dies and keep the workpiece level.

Drilling & Punching

Ensure proper die clearance to avoid burrs or delamination. Use multi-hole dies with stripper plates for multiple holes.

Support the workpiece when drilling, exit slowly, and apply coolant.

Bending

Follow the recommended bend radius, and adjust the die’s R angle based on thickness. Avoid sharp corners or folds to prevent conductivity issues.

Welding

Strip the copper layer to expose the aluminum before welding. Use AC TIG welding, followed by sandblasting and copper thermal spraying.

Riveting

Use extended rivets. The hole diameter should be 0.15–0.2 mm smaller than the rivet.

Surface Treatment

Passivation and plating options include zinc, nickel, and silver. Protect exposed aluminum ends before acid treatment to avoid corrosion.

Fastening

Use oversized washers and apply moderate torque to bolts.
