Titanium Copper Clad Bending Punching Busbar

Titanium Copper Clad Bending and Punching Busbar is a bimetallic laminated conductor composed of a high-conductivity copper core and an anti-corrosive titanium outer layer, specially designed for complex machining such as CNC bending, drilling, punching, tapping, and slotting.

These customizable Ti-Cu busbars are ideal for high-current applications in corrosive environments where standard copper bars would degrade. Thanks to the explosive bonding or hot roll bonding process, the titanium and copper layers form a robust metallurgical bond, allowing excellent mechanical performance even after multiple fabrications.

The production of Titanium Copper Clad Busbars with bending and punching features involves advanced bimetal bonding and precision CNC machining. Below is the step-by-step manufacturing process designed for custom-shaped, high-current, corrosion-resistant busbars:

1. Raw Material Selection

High-conductivity electrolytic copper (C11000 or T2)

Corrosion-resistant titanium sheets/bar (Grade 1 or Grade 2)

Inspection of material thickness, purity, and surface quality

2. Surface Preparation

Degreasing and acid pickling for both metal surfaces

Mechanical brushing or sandblasting to enhance bonding

Oxide layer removal to ensure metallurgical fusion

3. Explosive Bonding / Hot Roll Cladding

Metals are aligned and bonded using explosive welding or hot roll bonding

Achieves strong interfacial bonding without melting core materials

Forming a composite plate with uniform clad thickness

4. Heat Treatment (Optional)

Stress relief annealing to improve bonding strength

Adjust microstructure for improved machinability

5. Precision Cutting & Sizing

Cut to required dimensions (length, width, thickness)

Ensure tight tolerance for CNC fabrication

6. CNC Bending & Punching

Bending at precise angles as per drawings

Hole drilling, slotting, chamfering, and edge rounding

Ensures consistent shape and fit in electrical systems

7. Quality Inspection

Ultrasonic testing for bonding integrity

Shear and peel strength tests

Dimensional and surface finish inspections

8. Surface Treatment

Pickled or polished surface

Optional oxidation protection treatment

Deburring for safety and conductivity

9. Packaging & Delivery

Anti-rust wrapping with plastic film

Export-grade wooden crates

Custom labeling for traceability and installation guides
