Titanium Clad Copper Flat Bar

What is Titanium Clad Copper Flat Bar?

Titanium Clad Copper Flat Bar (Ti Clad Cu Flat Bar / Titanium Copper Composite Flat Bar / Titanium Clad Copper Bus bar) is a bimetallic composite material made by explosively bonding or roll-bonding pure titanium with high-conductivity copper.

It combines the corrosion resistance of titanium with the excellent electrical and thermal conductivity of copper, making it ideal for harsh electrochemical and power transmission environments.

High Conductivity + Excellent Corrosion Resistance for Electrochemical & Power Applications

High Conductivity: Copper core ensures superior electrical & thermal conductivity.

Strong Corrosion Resistance: Titanium layer resists acid, alkali, seawater, and electrochemical corrosion.

Permanent Bonding: ≥ 135 MPa bonding strength, no delamination.

Lightweight & Cost Saving: Lower titanium usage vs. solid titanium bars.

Excellent Weldability & Workability: Suitable for machining, bending, punching, drilling.

Long Service Life: Stable performance in high current & corrosive applications.

1. Raw Material Preparation

· Select high-purity electrolytic copper and ASTM B265 Grade 1 / Grade 2 titanium plates

· Surface inspection for cracks, impurities, lamination defects

· Cutting to required dimensions

Keywords:titanium plate, copper plate, raw material inspection, ASTM B265, C11000

2. Surface Treatment

· Titanium and copper are treated separately:

· Degreasing (alkaline cleaning to remove oil)

· Pickling (acid cleaning to remove oxides)

· Mechanical brushing / sandblasting to roughen bonding surface

· This step ensures a clean, activated surface for metallurgical bonding.

Keywords：surface activation, pickling, oxide removal

3. Vacuum Hot Rolling Composite

· Place titanium and copper plates in clean stacked order

· Load into vacuum furnace to remove oxygen

· High-temperature diffusion bonding under controlled pressure

· Rolling mill applies continuous pressure for solid bonding

This forms a 100% metallurgical bond, without glue or intermediate layer.

Keywords：vacuum bonding, diffusion bonding, titanium copper composite, hot rolling

4. Heating & Annealing

· Controlled temperature furnace

· Stress relief annealing to stabilize structure

· Improve ductility and long-term bonding stability

Keywords：annealing, stress relief, heat treatment

5. Mechanical Processing

· CNC cutting

· Milling, grinding, straightening

· Tolerance control (thickness, width, flatness)

· Edge trimming

Ensures the final Titanium Clad Copper Flat Bar meets dimensional accuracy.

Keywords：CNC machining, precision cutting, flatness control

6. Ultrasonic Testing & Bonding Inspection

· UT ultrasonic testing for internal bonding defects

· Bonding rate typically ≥ 98%

· Surface flaw detection

Keywords：NDT inspection, ultrasonic test, bonding quality

7. Final Surface Finishing

· Polishing

· Pickling

· Anti-oxidation packaging

Ensures excellent conductivity & corrosion resistance.
