Product Introduction
Titanium clad copper torsion bars are spiral-shaped special conductive components specifically developed for swing-type electroplating and electrolytic cell equipment. Unlike conventional straight composite bars, they utilize an integrated hot-twisting forming process based on exploded composite titanium-copper blanks, creating a uniform spiral texture structure on the surface. The product uses high-purity T2 oxygen-free copper as the conductive core, with an outer layer fully coated with a TA2 industrial pure titanium anti-corrosion layer. The spiral torsion gaps accelerate electrolyte circulation, eliminating dead zones in the plating solution and significantly improving the uniformity of current density around the anode and cathode plates, effectively preventing plating defects such as localized thin plating and pinholes. The metallurgical composite interface maintains stable low resistance under long-term reciprocating swing and high-current load conditions; the titanium cladding completely isolates acidic and chlorine-containing corrosive media, preventing copper ion precipitation and plating solution contamination. It is widely compatible with PCB vertical swing electroplating lines, hardware rack plating equipment, hydrometallurgical electrowinning cells, wastewater electrolytic oxidation, and other dynamically operating electrochemical equipment.

Product Features and Applications
Product Advantages
The spiral structure optimizes the fluid and significantly improves the uniformity of electroplating: the integrated hot twisting forms a continuous spiral gap, and the electroplating solution can quickly pass through the surface of the torsion bar, eliminating the dead corner of chemical residue behind the traditional straight bar; the difference in current density in different areas of the electrode plate is reduced by 70%, and the deep plating capability in the holes of high aspect ratio circuit boards is significantly improved, reducing the scrap rate.
Dynamic fatigue-resistant composite structure, suitable for fully automatic swing production line: The explosive + vacuum hot-rolled composite billet is stress-relief heat-treated and then twisted into shape. The bonding force of the titanium-copper interface is not damaged by the twisting deformation. It will not crack or delaminate under long-term reciprocating lifting and swinging conditions. Its service life is more than 1.5 times that of straight titanium-copper bars.
High current, low loss conductivity, and significant energy saving for long-term continuous production: High-purity oxygen-free copper core with atomic-level tight composite interface, with no additional contact resistance loss; saves more than 20% of electricity compared to pure titanium conductive rods, and is compatible with kiloampere-level high-current swing electroplating equipment, which greatly reduces the factory's electricity and operating costs in the long term.
Fully encapsulated titanium layer for long-lasting corrosion protection and prevention of bath solution contamination: The immersion area inside the bath is completely sealed with titanium material at 360°. Titanium quickly forms a stable passivation film in acidic and chlorine-containing electrolytes, with no copper ion leaching throughout the process, avoiding the decrease in the purity of electrolytic metals and pinhole defects in the PCB board plating, and reducing the frequency of electrolyte replacement.
Original factory one-stop twisting and forming processing reduces customers' overall costs: We have our own hot twisting and forming workshop and CNC precision machining center, so customers do not need to purchase straight bars for secondary twisting and forming, saving investment in bending, twisting and forming, and heat treatment equipment. Finished products can be directly assembled with anode racks and electroplating fixtures upon arrival.

Professional Consultation Q&A
Q1: What are the core advantages of titanium-clad copper torsion bars compared to ordinary straight titanium-copper composite bars?
A1: The core difference is the spiral twisted structure. Straight bars are prone to accumulating plating solution impurities on the back and forming current dead zones, resulting in uneven plating thickness on the board surface. The spiral gap of the torsion bar accelerates electrolyte circulation, eliminates fluid dead zones, and provides more uniform current distribution under continuous oscillation conditions. It also has stronger fatigue resistance, is suitable for automated oscillating electroplating production lines, and significantly reduces the defect rate of PCB and hardware electroplating.
Q2: After the titanium-clad copper torsion bar is torn, will delamination failure occur at the titanium-copper interface?
A2: No. Our company uses a process of "composite first, stress-relief annealing, and then constant-temperature hot twisting". The composite billet is vacuum annealed in advance to eliminate rolling internal stress, and then twisted at low speed and constant temperature by CNC equipment, so that the deformation stress is evenly distributed. The finished product undergoes 100% full-length ultrasonic flaw detection, and the bonding rate of the twisted deformation area is ≥98%. The million-cycle swing fatigue test shows no delamination or cracking problems.
Q3: Can titanium-clad copper torsion bars be cut and re-torsed on-site?
A3: On-site secondary processing and modification are not recommended. On-site cutting will damage the overall sealing and protective structure of the titanium layer, and secondary twisting without professional stress relief treatment can easily cause interface delamination and leakage. It is recommended that all rod diameter, torque, length, and end processing be integrated and molded in the factory, and all flaw detection tests be completed at the factory to ensure long-term dynamic operational stability.
