Titanium Clad Copper Composite Busbars in Multiple Shapes

Titanium Clad Copper Composite Busbar: Multiple Cross Sectional Shapes for Different Industrial Applications

In highly corrosive environments such as electrolysis, electroplating,hydro metallurgy, and the chlor-alkali industry, the choice of conductive material directly impacts equipment service life and production efficiency. Titanium clad copper composite has become the standard solution in these fields because it combines titanium's corrosion resistance with copper's high conductivity.

However, different application scenarios require different cross-sectional shapes for conductive materials. This article systematically reviews six cross-sectional shapes available for titanium clad copper and their typical applications, providing a reference for industry users.

1. Six Cross-Sectional Shapes and Specification Ranges

According to industry standards, titanium clad copper composite is available in six main cross-sectional shapes:

2. Technical Characteristics and Applications by Shape

2.1 Round Bar: Most Versatile

Round cross-section is the most mature shape for titanium clad copper, suitable for electrolyzer conductive bars, MMO (Mixed Metal Oxide) anode substrates, and ICCP (Impressed Current Cathodic Protection) system components.

Technical advantages:

Uniform current distribution, no risk of corona discharge

Easy to process—bending, turning, and welding are straightforward

Simple end sealing and reliable connection

Typical application: Conductive beams for suspending anode plates in hydrometallurgical electrolyzers.

2.2 Square Bar: Easy Positioning and Installation

Square cross-section has four flat sides, making it suitable for conductive components requiring precise fixation and positioning.

Technical advantages:

Easy to position in equipment, does not roll

Larger contact surface with fixtures and brackets for stable connection

Typical application: Conductive clamping components in PCB electroplating equipment and automated electroplating production lines.

2.3 Rectangular/Flat Bar: Preferred for High Current Busbars

Rectangular (or flat) shape is the standard form for titanium clad copper busbars and the preferred choice for high-current transmission applications.

Technical advantages:

For the same cross-sectional area, flat shape provides larger surface area for better heat dissipation

Higher current-carrying capacity

Easy to stack or arrange closely for efficient space utilization

Manufacturing requirement: When width-to-thickness ratio≥6, specialized processes are required to ensure cladding quality.

Typical application: Main conductive busbars in chlor-alkali electrolyzers—for example, the 25.4×12.7 mm specification at 2900 mm length is a mature product solution in the industry.

2.4 Drum Shape: Specialized for Electrolyzers

Drum-shaped cross-section is designed for specific electrolysis equipment. Common specifications includeΦ25×14, Φ27×14, Φ29×14, Φ32×14, and Φ34×14 mm.

Technical advantages:

Optimized current distribution due to specialized cross-sectional profile

Rounded corners reduce stress concentration

High compatibility with specific electrode fixtures

Typical application: Specialized conductive bars for metal anode electrolyzers.

2.5 Wire: Small Diameter for Fine Components

Wire products can be as small asΦ2.0 mm, suitable for conductive components requiring bending or weaving.

Technical advantages:

Good formability, easy to bend into shape

Can be used to fabricate anode baskets, conductive mesh, and similar structures

Typical application: Small-diameter anodes or conductive wires, as well as components welded together with other shapes.

2.6 Combined/Welded Shape: For Custom Designs

Different cross-sectional shapes can be welded together to meet complex equipment installation requirements.

Technical advantages:

Maximum design flexibility

Different cross-sectional profiles can be achieved within a single conductive component

Typical application: Shaped electrodes, non-standard equipment conductive components.

3. Shape Selection by Industry

4. Selection Recommendations

When choosing the appropriate cross-sectional shape, users can follow these principles:

Prefer standard shapes when possible: Round and rectangular shapes have mature supply chains and stable pricing. Choose these unless special requirements exist.

Determine dimensions based on current requirements:

Low current: Round (Φ20 or smaller) or small square

Medium current: Round (Φ20-50) or rectangular (width≤50 mm)

High-current busbars: Rectangular (width≥50 mm)

Choose shape based on installation method:

Positioning required / anti-roll needed: Square or rectangular

Flexible installation with multi-angle connection: Round

Non-standard shapes can be customized:can support custom cross-sectional shapes based on engineering drawings.
