Product Introduction
Titanium-clad copper-clad steel is a high-performance three-layer bimetallic composite material prepared using explosive welding and precision drawing processes. From the outside in, it consists of a pure titanium anti-corrosion and acid-resistant layer, a high-purity copper conductive transition layer, and a carbon steel load-bearing core layer. All three layers achieve 360° circumferential metallurgical bonding. Unlike titanium-clad steel double-layer rods, this three-layer design perfectly integrates three core performance characteristics: the outer titanium layer provides excellent resistance to strong acids and chloride ions; the middle copper layer ensures high electrical and thermal conductivity; and the central steel core provides high-strength structural support and cost-effectiveness. Compared to pure titanium rods, material costs are reduced by 50%-70% while meeting corrosion resistance requirements, and structural strength is higher. Compared to titanium-clad steel rods, conductivity is improved by more than 2 times, and heat loss is lower under high-current conditions. It is widely used in electrolytic smelting cathode beams, electroplating fixtures, conductive busbars, and anti-corrosion conductive structural components, making it a cost-effective solution for strong acid conductive structural applications.

Product Features and Applications
Product Advantages
The three-layer integrated design combines the three advantages of titanium (resistance to strong acids), copper (high electrical and thermal conductivity), and carbon steel (high strength and low cost) through metallurgical integration . This solves the problems of double-layer titanium steel rods (poor conductivity and easy heating under high current) and titanium-clad copper rods (insufficient strength and easy deformation over large spans). One material simultaneously meets the triple requirements of corrosion resistance, electrical conductivity, and load-bearing capacity.
Dual-interface full metallurgical bonding, stable and reliable performance : Explosive welding + precision drawing process achieves atomic-level metallurgical bonding of dual interfaces. The bonding strength is far higher than mechanical coating and electroplating coating. There is no risk of blistering, peeling or delamination during long-term use. It can withstand deep processing such as drawing, bending and turning. The conductivity is continuous and stable with no contact resistance loss.
Extremely high cost-effectiveness and lower overall cost : Only the functional outer layer and conductive layer use precious metals, while the main body is supported by low-cost carbon steel. Under the same corrosion resistance and conductivity, it saves 50%-70% of material costs compared to pure titanium rods, and improves structural strength by more than 40% compared to titanium-clad copper rods. At the same time, it significantly reduces heat generation energy consumption under high current conditions, resulting in significant comprehensive benefits in the long term.
Flexible thickness ratio customization : The thickness ratio of titanium layer, copper layer and steel core can be flexibly adjusted according to working conditions: the copper layer can be thickened for high conductivity requirements, the titanium layer can be thickened for heavy corrosion conditions, and the steel core ratio can be increased for high load conditions, accurately matching the performance requirements of different scenarios.
Excellent secondary processing capability : It supports deep processing such as centerless grinding, turning, drilling, bending, welding, and surface passivation, and can be directly processed into finished conductive hangers, conductive beams, electrode tips and other components, with a matching exclusive dissimilar metal welding process solution.
Application Areas
Hydrometallurgy: Electrolytic copper/zinc/nickel cathode conductive beams, electrolytic cell conductive rods, and conductive components for acidic systems in hydrometallurgical processes.

Professional Consultation Q&A
Q1: In many electrolysis scenarios, titanium-clad steel can be used, so why choose a three-layer structure of titanium-clad copper-clad steel?
A1: Titanium-clad steel only offers corrosion resistance and load-bearing capacity; the steel core has poor conductivity, leading to severe heat generation and uneven current distribution under high-current conditions. This can result in low electrolysis efficiency, inconsistent plating thickness, and accelerated interface aging due to prolonged heating. Titanium-clad copper-clad steel, on the other hand, adds a highly conductive copper layer between the titanium layer and the steel core. This retains the strong acid resistance of titanium and the high strength and low cost of steel, while significantly improving overall conductivity through the copper layer. This reduces heat loss under high current, results in more uniform current distribution, and better product consistency during electrolysis/electroplating, making it particularly suitable for continuous production conditions with high current and high capacity.
Q2: Can titanium-clad copper-clad steel be used in high-temperature acidic electrolysis? What is the upper limit of the long-term operating temperature?
A2: Under normal operating conditions, the long-term stable service temperature of titanium-clad copper-clad steel is -50℃ to 250℃, fully compatible with most room-temperature and medium-temperature acidic electrolytic and electroplating processes. The passivation film of the titanium layer is stable and its corrosion resistance is reliable in acidic media below 250℃; the mechanical properties of the copper layer and steel core also remain stable. If used for extended periods above 250℃, the oxidation rate of the titanium layer will accelerate, and the risk of interfacial element diffusion will increase; therefore, long-term use at excessively high temperatures is not recommended. For higher temperature and stronger corrosion conditions, we can recommend a zirconium-based three-layer composite rod solution.
Q3: For long-span conductive beams, what structural optimizations can be made to titanium-clad copper-clad steel to improve bending resistance?
A3: Optimization can be achieved in two dimensions: First, the structural form, changing the round bar to a flat/square bar to increase the height dimension of the cross-section, significantly improving the bending modulus while maintaining the same copper layer ratio and ensuring unaffected conductivity; second, the thickness ratio, appropriately increasing the steel core ratio to enhance structural strength while optimizing the copper layer cross-sectional distribution to ensure sufficient conductive cross-sectional area, all while keeping the total cross-section unchanged. Additionally, the steel core material can be upgraded, using high-strength alloy steel instead of ordinary carbon steel to further improve bending resistance. We can provide a customized ratio design scheme based on your span, load, and conductivity requirements.
