Product Introduction
Titanium clad copper conductive beams are integrated heavy-duty conductive load-bearing components developed for various electrolytic cells and automated electroplating production lines. Unlike ordinary simple composite busbars, the beam's cross-sectional structure is optimized for long-term heavy-load electrode plate suspension. The product employs an explosive welding + vacuum hot rolling composite process, using high-purity oxygen-free copper as the internal conductive core material. The entire immersion area in the electrolytic bath is fully encapsulated with a TA2 pure titanium anti-corrosion layer. The metallurgical interface eliminates the contact resistance increase caused by delamination, and the titanium cladding completely isolates various corrosive electrolytes, preventing copper ion precipitation and contamination of the electrolyte. This single component simultaneously bears three core functions: high-current transmission, electrode plate suspension and load-bearing, and dielectric corrosion protection. It is widely used in copper-zinc-nickel hydrometallurgical electrowinning, chlor-alkali membrane electrolysis, PCB vertical swing electroplating, electrolytic copper foil production, and industrial wastewater electrolytic oxidation equipment, effectively reducing energy consumption and equipment maintenance frequency in electrochemical plants.

Product Features and Applications
Product Advantages
The electrolytic cell combines conductive and load-bearing functions, simplifying the overall structure of the electrolytic cell: a single titanium-clad copper conductive beam simultaneously serves as both the conductive busbar and the electrode plate suspension beam, eliminating the need for separate anti-corrosion sleeves and independent load-bearing supports. This reduces the number of electrolytic cell components, lowers equipment procurement and assembly costs, and results in a simpler cell layout.
Atomic-level metallurgical composite, no delamination under long-term heavy load: Explosive composite + vacuum hot rolling diffusion process allows the titanium-copper interface to be completely fused. With stress relief heat treatment, no interface delamination will occur under drilling, bending, and long-term load deformation. Compared with adhesive coating products, the service life is increased by more than 3 times.
Significantly reduces electrolysis energy consumption, saving electricity costs in long-term production: High-purity oxygen-free copper core with atomic-level tight composite interface, no additional contact resistance loss; saves more than 20% of electricity compared to pure titanium conductive rod, and is compatible with kiloampere-level high-current swing electroplating equipment, significantly reducing factory electricity operating costs in the long run.
Fully enclosed titanium anti-corrosion layer ensures the purity of electrolyte and product: there is no exposed copper material in the immersion area of the tank, the titanium passivation film isolates acidic and chlorine-containing corrosive media, and will not generate copper ions to contaminate the electrolyte. There are no pinholes on the PCB electroplating board surface, the purity of the metal in the wet metallurgical electrolysis is stable, and the electrolyte replacement cycle is extended.
Heavy-duty bending-resistant structure, suitable for large-scale electrolysis production lines: The thickened composite substrate rectangular cross-section design has excellent bending mechanical properties. A single beam can suspend dozens of anode and cathode plates. The 10,000-ton-level hydrometallurgical electrolysis workshop can operate continuously all year round without bending or sagging, reducing the frequency of downtime for adjustment.
One-stop original factory precision machining reduces customer processing costs: Our own CNC machining, titanium welding, and heat treatment workshops support drilling, lug welding, bending, and threading of any size. Finished products can be directly hoisted and used upon arrival, eliminating the need for customers to purchase metal processing equipment for secondary processing.

Professional Consultation Q&A
Q1: What are the long-term advantages of titanium-clad copper conductive beams compared to pure copper conductive beams?
A1: Pure copper conductive beams are highly susceptible to corrosion when in direct contact with acidic or chlorine-containing electrolytes, and copper ions continuously contaminate the electrolyte, requiring frequent replacement. Titanium-coated copper conductive beams, on the other hand, have a titanium layer covering the entire immersion area, completely isolating them from corrosive media. This ensures stable electrolyte purity and a service life 5-8 times longer than pure copper beams, significantly reducing downtime replacement costs and electrolyte loss.
Q2: After drilling holes and welding lugs onto the titanium-clad copper conductive beam, will delamination failure occur at the titanium-copper interface?
A2: No. Our process sequence is to first perform composite bonding and stress relief through annealing, followed by drilling and welding for deep processing. The stress is evenly distributed during the processing. All finished products undergo full-length ultrasonic testing, and the bonding rate of the opening and welding areas is ≥98%. There are no delamination or leakage issues during heavy-duty long-term use.
Q3: How to select the thickness of the titanium layer in a large-scale hydrometallurgical electrolysis workshop that operates 24 hours a day?
A3: For intermittent production of 8 hours per day, a 1.0–1.5 mm titanium layer is recommended; for continuous operation 24 hours a day, year-round, and for electrolyte systems containing high concentrations of chloride ions/sulfuric acid, a 2.5–4.0 mm thicker titanium layer is recommended, as it has stronger resistance to erosion and pitting corrosion and can be used stably for more than 5 years without replacement.
