Product Introduction
Titanium-clad copper rods for electrolytic copper foil production are the core bimetallic composite anode substrate in the foil-making unit, integrating the functions of uniform high-current transmission and anode structural support. The product adopts a fully encapsulated structure of a highly conductive pure copper core and a corrosion-resistant pure titanium outer layer, manufactured through explosive bonding and precision rolling processes to achieve metallurgical-grade atomic bonding.
As the core anode conductive component of the copper foil production system, this product is installed inside the electrolytic cell, providing a stable and uniform electric field output for copper ion electrodeposition. Unlike pure titanium anodes, which suffer from high resistivity and high energy consumption, and pure copper anodes, which corrode rapidly and easily contaminate the electrolyte, titanium-clad copper anode rods maintain a stable, low-resistivity current output over a long period, significantly extending their service life, preventing abnormal copper ion deposition, and effectively improving the uniformity of copper foil thickness and surface quality. This product is widely used in the production of lithium-ion battery copper foil, high-frequency and high-speed electronic copper foil, and RTF reverse copper foil, and is a key material for improving the yield of ultra-thin copper foil and reducing overall production costs.

Product Features and Applications
Product Advantages
Metallurgical-grade composite interface with lower conductivity loss: The atomic-level metallurgical bonding of titanium and copper is achieved by using explosive bonding and precision rolling processes. The interface is gapless and has no additional contact resistance, which significantly reduces conductivity loss compared to mechanically coated products. The voltage is lower and the temperature rise is smaller under high current operation, and the overall power saving rate can reach 8%-12%, which significantly reduces the power cost of copper foil production.
High-purity substrate ensures uniform conductivity and improves copper foil yield: The core uses high-purity T2 copper, which ensures uniform and stable current distribution. Combined with high-precision rod shape and position tolerance, it can effectively maintain the consistency of the anode and cathode spacing, improve the lateral thickness difference of the copper foil, reduce defects such as pinholes, burrs, and copper powder, and significantly improve the finished product qualification rate of 4.5μm and 6μm ultra-thin copper foil.
Full titanium coating for corrosion protection and ultra-long service life: The working area of the rod is fully covered with a titanium layer, which completely isolates the acidic copper sulfate electrolyte from contact with the copper core. Its corrosion resistance is more than 10 times that of traditional pure copper electrodes. It greatly reduces the frequency of downtime to replace the anode, improves the production line uptime, and has significant advantages in overall cost throughout the entire life cycle.
High-precision machining control, suitable for high-end production lines: multi-pass precision rolling and straightening process, strictly control the straightness, roundness and titanium layer thickness uniformity of the bar, and the dimensional accuracy meets the installation requirements of high-end foil production equipment; it can be directly matched with standard foil production units, or customized with bending and irregular structures to adapt to special production lines.
No impurities are released, ensuring the purity of copper foil: The titanium layer has stable chemical properties and does not react with the electrolyte during the electrolysis process. There is no abnormal release of copper ions or impurity ions, which will not contaminate the bath system and avoid quality problems such as impurity spots and uneven color of copper foil. It can stably guarantee the surface purity and performance of lithium battery copper foil and high-end electronic copper foil.
Excellent structural strength and simplified production line design: The bimetallic composite structure combines the conductivity of copper with the structural strength of titanium, exhibiting excellent bending rigidity and no significant deformation under large-span installation. It can be directly used as an anode conductive beam without the need for additional support structures, simplifying the internal design of the electrolytic cell and reducing the cost of supporting installation.

Professional Consultation Q&A
Q1: What is the difference between titanium-clad copper rods specifically designed for electrolytic copper foil and ordinary titanium-clad copper rods?
A1: The core difference lies in precision control and scene adaptation.
● Ordinary titanium-clad copper rods are mainly designed for general conductivity and corrosion resistance, with lower requirements for dimensional accuracy, straightness, and titanium layer uniformity. They are suitable for conventional electrolysis and electroplating applications.
● The titanium-clad copper rod for electrolytic copper foil has been specifically optimized for the foil production process. It strictly controls the dimensional and positional precision of straightness, roundness, and uniformity of titanium layer thickness, ensuring consistent anode and cathode spacing and uniform current distribution. It meets the high precision requirements of ultra-thin copper foil production and is a dedicated anode substrate for copper foil production systems.
Q2: Will the titanium-clad copper rod contaminate the electrolyte during operation?
A2: No. The product's working area is fully covered with a titanium layer. Titanium is chemically stable and will not react or precipitate impurities in copper sulfate electrolyte. At the same time, the metallurgical-grade composite interface is seamless and does not peel off, preventing issues such as copper core exposure or abnormal copper ion precipitation. This ensures long-term electrolyte cleanliness and avoids impurities and defects in the copper foil.
Q3: Can titanium-clad copper rods be bent or made into irregular shapes? Will the bent parts delaminate?
A3: Yes, we can customize bending and irregular shapes. We use a special mold cold bending forming process to strictly control the bending radius and deformation. The composite layer at the bending point will not crack or delaminate, which can adapt to the special anode structure requirements of foil making machines. Before bending, we will conduct process verification based on the size and angle to ensure that the bonding performance of the finished product meets the standards.
