Product Introduction
Our titanium clad copper conductive flying bar adopts Grade2 pure titanium outer cladding + high-purity C11000 ETP copper inner core, manufactured via explosion welding + hot rolling metallurgical composite process, interface shear strength ≥135MPa without delamination or gap, fully compliant with ASTM B152 copper standard, ASTM B265 titanium standard and GB/T 12769 titanium-copper composite material specificationMade-in-Ch.... It serves as the core main conductive crossbeam of VCP PCB electroplating cathode flying target, replacing traditional solid ETP pure copper flying beam. The inner copper core provides ultra-high electrical conductivity to minimize circuit voltage drop under large current; the outer seamless titanium cladding directly contacts acidic copper plating bath, isolating copper core from sulfuric acid, copper sulfate corrosive liquid to avoid copper oxidation, copper powder shedding and bath contamination.
Different from solid pure copper flying bar, all MMO titanium anode plates, lead alloy anode and steel base anode: Ti-Cu composite flying bar belongs to cathode conductive structural part, combining copper's ultra-low resistance and titanium's full acid/chloride corrosion resistance in one material. Solid copper beam easily oxidizes and produces copper powder after long-term immersion, polluting plating solution and causing PCB pinhole defects; single titanium bar has extremely high resistivity leading to severe voltage drop and uneven copper thickness. Complete CNC precision machining, the connection end is milled to strip titanium layer and expose copper core for copper-to-copper conductive connection, eliminating contact overheating and arcing risk. Stable service life reaches 4–7 years under 24h continuous VCP high-current plating condition, far longer than solid copper beam. Support full customization of cross-section size, total length, titanium cladding thickness, exposed copper end length according to customer VCP tank size and flying target load demand. We have over 10 years experience producing Ti-Cu composite conductive beams for PCB VCP lines, compatible with JET, KINWA, MEC, EVERITECH mainstream VCP equipment, widely supplied to HDI, FPC, rigid multilayer PCB factories globally.

Core Product Advantages
Dual material composite, perfectly balance high conductivity & full acid corrosion resistance Inner ETP copper core retains top industrial conductivity, effectively reduce high-current voltage drop, guarantee uniform current distribution on all suspended PCB boards and stabilize copper thickness tolerance within ±6%. Outer Grade2 titanium cladding completely isolates copper core from acidic plating liquid, fundamentally solve solid copper beam oxidation, copper powder shedding defects, avoid PCB pinholes, blemishes and frequent bath replacement cost.
Explosion hot rolling metallurgical bonding, zero gap interface without delamination Adopt explosion compound + multi-pass hot rolling integrated process, titanium and copper form tight metallurgical combination instead of simple mechanical wrapping, shear strength up to 135MPa, can withstand long-term reciprocating swing, thermal cycle and large current impact without interlayer separation, no local overheating resistance rise hidden danger.
Longer service life & lower full-cycle maintenance cost than solid copper beam Solid pure copper flying beam needs polishing and re-passivation every 3–6 months, and will be severely thinned after 2–3 years for replacement; Ti-Cu clad flying bar titanium outer layer will not corrode in acidic copper bath, only simple regular cleaning required, service life extended to 4–7 years, reduce flying target frame replacement frequency by over 60%, cut bath consumption and maintenance labor cost largely.
Full OEM customization, universal interchangeable with mainstream VCP flying target frames Support custom cross-section size, beam length, titanium cladding thickness, exposed copper conductive end length according to customer electrolytic tank internal width and single flying target PCB load capacity. The exposed copper core end realizes copper-copper contact with conductive hanging head, avoid titanium direct contact high contact resistance arcing risk, perfectly match all mainstream brand VCP flying target assemblies without equipment modification.

Professional Consultation Q&A
Q1: What is the core difference between Titanium Clad Copper Conductive Flying Bar, solid pure copper flying beam, various MMO titanium anode plates, lead alloy & steel based anode?
A1: Ti-Cu clad flying bar is cathode structural conductive crossbeam for VCP flying target, dual composite material integrating copper high conductivity and titanium acid resistance; solid copper beam has high conductivity but easy oxidation shedding copper powder to pollute plating liquid, short service life. All anode plates are positive electrolytic reaction electrodes (Ru-Ti/Ir-Ta/PbO₂ etc.), used for oxidation reaction in plating bath, different function and installation position from cathode flying bar. Lead alloy/steel anode has poor conductivity and metal ion dissolution risk, cannot be used as high-current conductive beam.
Q2: Why choose titanium clad copper instead of single solid titanium or solid copper for VCP main flying bar?
A2: Single solid titanium bar has very high resistivity, severe voltage drop under large current, resulting in inconsistent PCB copper thickness; solid pure copper beam directly contacts acidic plating liquid, oxidizes rapidly to produce copper powder causing PCB pinhole defects, frequent maintenance and short service life. Ti-Cu composite perfectly solves both defects simultaneously, lower long-term comprehensive cost.
Q3: Will titanium-copper composite layer delaminate after long-term reciprocating swing and high current operation?
A3: Our product adopts explosion + hot rolling metallurgical bonding, interface shear strength ≥135MPa, passed long-term swing fatigue test and thermal cycle test, no delamination risk under normal VCP production working condition; ultrasonic full inspection before delivery to eliminate hidden interlayer gaps.
Q4: Can we customize beam length, cross-section size and titanium cladding thickness?
A4: Full personalized OEM customization supported. Total length, width & thickness of cross section, titanium outer cladding thickness, exposed copper core length at both ends can be fully adjusted according to customer VCP plating tank inner size and daily production load.
