As a specialized supplier of bimetallic materials, we provide high-quality Titanium-Copper Clad Bars engineered for demanding electrochemical applications. This innovative composite material is designed to maximize electrical conductivity while providing robust protection against highly corrosive electrolytes. By cladding a core of high-purity copper with a layer of commercially pure titanium, our clad bars deliver superior performance and longevity in industries such as electroplating, hydrometallurgy, and metal refining.

Why Choose Titanium-Copper Clad Bar? The Perfect Bimetallic Synergy

Titanium-Copper Clad Bar is a strategic material choice that solves the critical engineering challenge of balancing electrical efficiency with corrosion protection.

Key Titanium-Copper Clad Bar benefits include:

• Exceptional Electrical Conductivity: The copper core ensures minimal electrical resistance and maximum current efficiency, crucial for high-power electrochemical processes.

• Superior Corrosion Resistance: The titanium outer layer provides complete immunity to aggressive chemical media, preventing contamination of the electrolyte and extending the lifespan of the conductor.

• Cost-Effectiveness: Using a thin, protective layer of titanium over a thick copper core is significantly more economical than using solid titanium conductors, which have poor electrical properties.

• High Bond Strength: The metallurgical bond created by explosive or rolling cladding ensures excellent heat transfer and prevents delamination, maintaining stable electrical performance under high current loads.

Comprehensive Guide to Clad Bar Specifications and Bonding Methods

Our clad bars are manufactured to precise standards, ensuring optimal performance for use as anode and cathode conductors.

Standard Material Combinations

Bonding Technology: Explosive and Rolling Cladding

We utilize advanced cladding techniques to achieve a perfect metallurgical bond between the titanium and copper.

• Explosive Cladding: Creates a high-strength, void-free bond interface, ideal for large cross-sections and high-current applications.

• Rolling Cladding: Used for smaller cross-sections and continuous production, offering excellent dimensional accuracy and surface finish.

The resulting bond is essential for minimizing contact resistance and ensuring efficient current transmission from the copper core to the titanium surface.

Precision Manufacturing & Quality Assurance

Our manufacturing process focuses on maintaining the integrity of the bond and the electrical properties of the bar.

We prioritize quality control through:

• Ultrasonic Testing: 100% inspection of the bond interface to detect any unbonded areas.

• Electrical Conductivity Testing: Verification of the bar's overall conductivity to ensure minimal power loss.

• Shear Strength Testing: Confirmation of the metallurgical bond strength.

• Dimensional Tolerance: Precision machining to meet strict geometric requirements for seamless integration into electrolysis cells.

Applications of Titanium-Copper Clad Bar Across Key Industries

The unique properties of Ti-Cu Clad Bar make it indispensable in processes requiring high current density in corrosive media.

Electroplating and Surface Finishing

Used as anode and cathode hanger bars in electroplating baths (e.g., Chrome, Nickel, Copper plating), where the titanium protects the copper from the acidic electrolyte while ensuring efficient current delivery.

Hydrometallurgy and Metal Refining

Essential for the production of non-ferrous metals like Zinc, Copper, and Manganese through electrowinning and electrorefining processes. The clad bar serves as the main conductor in the electrolytic cells.

Printed Circuit Board (PCB) Manufacturing

Utilized in the high-speed copper plating lines for PCB production, where precise current control and resistance to etching chemicals are required.

How to Select the Right Titanium-Copper Clad Bar

Selecting the correct clad bar requires balancing electrical load, corrosion protection, and mechanical support.

1. Determine Current Density: The required current load dictates the necessary cross-section of the copper core.

2. Specify Titanium Thickness: The thickness of the titanium layer is determined by the corrosiveness of the electrolyte and the expected lifespan. Typical thicknesses range from 1.0mm to 3.0mm.

3. Choose Bar Shape and Size: We offer standard and custom shapes, including round, square, and rectangular bars, to fit various cell designs.

4. Standards Compliance: Ensure the material meets relevant standards like ASTM B898.

Fabrication Best Practices for Clad Bars

Proper fabrication is crucial for maximizing the performance of Ti-Cu Clad Bars.

• Welding/Joining: Connections to the copper core (e.g., to busbars) must be made by exposing the copper at the ends and using standard copper welding or brazing techniques to ensure low-resistance electrical joints.

• Sealing: The exposed copper ends must be properly sealed (e.g., with epoxy or rubber caps) to prevent the corrosive electrolyte from wicking into the copper core.

• Bending: While the bars can be bent, care must be taken to ensure the bend radius does not compromise the metallurgical bond, especially in the titanium layer.
