Product Introduction
Titanium-clad copper busbars, also known as titanium-copper composite conductive busbars or electrolytic cell conductive busbars, are core bimetallic composite conductive components for power transmission and distribution between the anode and cathode in electrolysis systems. They possess both high current-carrying capacity and strong corrosion resistance. The product employs a highly conductive pure copper core and a corrosion-resistant pure titanium outer layer, fully encapsulated through explosive bonding and hot-rolling diffusion processes to achieve metallurgical-grade atomic bonding.
The product is installed inside or beside the electrolytic cell as the main current-carrying busbar, directly contacting corrosive electrolytes such as acidic, alkaline, and chloride-containing solutions. Unlike traditional pure copper busbars, which suffer from rapid corrosion and high maintenance costs, and pure titanium busbars, which have high resistivity and high energy consumption, titanium-clad copper busbars offer stable resistance under long-term high-current operation, significantly extending service life, preventing copper corrosion and electrolyte contamination, and effectively reducing cell voltage and overall electricity costs. It is widely used in hydrometallurgical electrowinning, chlor-alkali electrolysis, electrolytic copper foil production, alkaline water electrolysis for hydrogen production, and impressed current cathodic protection, among other engineering applications.

Product Features and Applications
Product Advantages
Metallurgical-grade composite interface, high current and low loss operation: he explosive composite + hot rolling diffusion process achieves atomic-level metallurgical bonding of titanium and copper. The interface is gapless and has no additional contact resistance. Compared with mechanical coating and bolt splicing solutions, the conductivity loss is greatly reduced. Under high current carrying conditions, the pressure is reduced and the temperature rise is small. The overall power saving rate can reach 10%-15%, which significantly reduces the power cost of electrolysis production.
Full titanium layer sealed protection, ultra-long service life: The working area of the busbar is fully covered with titanium layer, and the welds are sealed with titanium material, which completely isolates the corrosive electrolyte from contact with the copper core. Its corrosion resistance is more than 10 times that of traditional pure copper busbars. It greatly reduces the frequency of downtime for replacement, grinding and maintenance, improves the continuous operation capability of the electrolysis production line, and has significant advantages in overall cost throughout the entire life cycle.
Large cross-section customization capability to adapt to high-load electrolysis: Supports customization of large cross-sections up to 200×100mm, which can carry tens of thousands of amperes of current, and is suitable for the load requirements of large electrolytic cells and high-capacity electrowinning production lines; it can achieve ultra-large current convergence through multi-row parallel connection and segmented splicing to meet the power distribution needs of electrolysis systems of different scales.
Various connection options and convenient and reliable installation: multiple connection forms can be customized according to site conditions: pre-drilled bolt holes enable rapid assembly of fasteners, machined welding bevels enable on-site argon arc welding, and matching titanium-copper transition joints enable low-resistance connection of busbars of different materials; finished products are prefabricated as needed, reducing on-site secondary processing and shortening the installation cycle.
No impurities are released, ensuring the purity of electrolytic products: The titanium layer is chemically stable and does not react in various electrolytes, preventing the release of copper ions or impurity ions and thus avoiding contamination of the electrolyte system; avoiding quality problems such as excessive impurities and uneven color in cathode products, and stably ensuring the purity and grade of electrolytic copper, electrolytic nickel, cathode copper foil and other products.
Excellent structural strength and simplified tank design: The bimetallic composite structure combines the high conductivity of copper and the high strength of titanium, with excellent bending rigidity. It exhibits no significant deformation under large-span installation and can be directly used as a conductive support beam inside the tank without the need for additional support structures. This simplifies the internal design of the electrolytic cell and reduces the cost of supporting installation and auxiliary materials.

Professional Consultation Q&A
Q1: What are the core advantages of titanium-clad copper busbars used in electrolysis compared to ordinary pure copper busbars and pure titanium busbars?
A1: The core advantage lies in balancing conductivity and corrosion resistance, overcoming the inherent shortcomings of single materials: pure copper busbars have good conductivity but are not corrosion-resistant, corroding and being lost within 3-6 months under electrolytic conditions, contaminating the electrolyte; pure titanium busbars are corrosion-resistant but their conductivity is only about 3% of copper's, resulting in large voltage drops and high energy consumption under high current. The titanium-clad copper busbar features an internal copper core ensuring high conductivity and low loss, while an outer titanium layer resists corrosion, resulting in a service life more than 10 times that of pure copper busbars, while also saving more than 30% more energy than pure titanium busbars, offering the best overall benefits throughout its lifecycle.
Q2: Under high-current electrolysis conditions, will the titanium-clad copper busbar generate significant heat?
A2: Overheating will not occur under normal design conditions. The product's core is made of high-purity T2 copper with a conductivity ≥98% IACS. The metallurgical-grade composite interface has no additional resistance, and the overall current-carrying capacity is close to that of a pure copper busbar. Simultaneously, the flat busbar structure provides a large heat dissipation area, ensuring that the temperature rise under normal rated current is controlled within national standards. We will calculate the cross-sectional dimensions based on your actual operating current to ensure stable temperature rise during long-term high-current operation.
Q3: How are the titanium-clad copper busbars connected? Will welding damage the composite layer?
A3: We support both bolted connections and welding, neither of which will damage the performance of the composite layer. Bolted connections are secured through pre-drilled holes, making installation and disassembly convenient. Welding uses a special titanium-copper welding process, which is applied to the exposed copper area at the end or at the transition joint. The work area avoids the composite interface. After welding, a sealing and anti-corrosion treatment is applied to ensure connection strength and low-resistance conductivity without affecting corrosion resistance.
