Product Introduction
Our titanium clad copper conductive terminals adopt high-energy explosion welding + multi-pass hot rolling metallurgical composite forming process. Outer cladding: Grade2 pure titanium (UNS R50400); inner core: C11000 OFHC high-purity oxygen-free electrolytic copper (Cu ≥99.99%). Interface shear strength ≥135MPa, 100% ultrasonic inspection without interlayer delamination or gaps, fully compliant with ASTM B152 copper standard, ASTM B265 titanium standard and GB/T 12769 bi-metal clad material specification. It is the key transition conductive connector at both ends of VCP PCB vertical continuous plating line conductive components, divided into two application categories:
● Anode side terminals: Connect Ti-Cu anode rod / MMO titanium anode plate / titanium basket frame to rectifier copper busbar.
● Cathode side terminals: Connect Ti-Cu flying target composite beam / flying target frame plate to negative copper busbar. The internal high-conductivity copper core provides ultra-low contact resistance to eliminate large DC voltage drop at connection joints; seamless Grade2 titanium outer layer directly contacts acidic sulfuric copper plating liquid, completely isolates copper core from corrosive electrolyte, fundamentally solving oxidation, copper powder shedding and bath liquid pollution defects of solid pure copper terminal lugs.
Differentiation vs other similar products:
● Solid pure copper terminal: high conductivity but rapid acid oxidation, copper powder leads to PCB pinhole defects, short service life;
● Solid pure titanium terminal: ultra-high resistivity, severe joint voltage drop causing uneven PCB copper thickness;
● Ti-Cu anode rod / flying target bar: long linear conductive carrier, while conductive terminals are independent machined end connection fittings;
● MMO coated titanium anode plate: catalytic electrolytic electrode, matched with Ti-Cu terminals for conductive transition only, different core function;
● Lead alloy / steel base anode: poor conductivity, continuous metal ion dissolution, cannot be used as high-current transition conductive terminals. Support CNC milling, drilling, tapping, bending full precision machining; one contact face is fully milled to strip titanium cladding and expose pure copper core for copper-to-copper low-resistance bolt docking, avoiding titanium-titanium contact electric spark and high contact resistance risks. Stable service life reaches 4–7 years under 24h non-stop high-current VCP plating production, far exceeding solid copper conductive terminals. Full customization of terminal outline, hole spacing, titanium cladding thickness, exposed copper contact area per customer anode/cathode assembly drawings. We have over 10 years experience manufacturing Ti-Cu composite conductive terminals compatible with JET, KINWA, MEC, EVERITECH mainstream VCP plating equipment, widely exported to HDI, FPC, rigid multilayer PCB manufacturers worldwide.

Core Product Advantages
Dual metal atomic metallurgical composite, balance maximum conductivity & full acid corrosion resistance Internal OFHC copper core retains top industrial electrical conductivity, minimizes joint contact resistance under heavy DC load, ensures consistent current transmission between conductive carrier and rectifier busbar, stabilizes PCB copper thickness tolerance within ±6%. Outer Grade2 seamless titanium cladding fully separates copper core from acidic corrosive plating liquid splashes, completely eradicates solid copper terminal oxidation & copper powder shedding, drastically reduces PCB reject rate caused by pinholes and surface blemishes.
Explosion hot rolling integral bonding, tight interface without interlayer separation risk Adopt high-energy explosion welding first to realize atomic-level metallurgical fusion between titanium and copper, then multi-pass hot rolling to compact composite layers and control cladding thickness tolerance ±0.05mm. Interface shear strength ≥135MPa, withstand long-term vibration, thermal cycle fluctuation and large DC current impact without delamination; each finished Ti-Cu conductive terminal passes 100% ultrasonic flaw detection before delivery to eliminate hidden interlayer gaps.
Far longer service life & sharply reduced joint maintenance frequency vs solid copper terminal Solid pure copper conductive terminal needs disassembly, polishing and re-passivation every 3–6 months, and will be severely corroded & thinned after only 2–3 years requiring full conductive component replacement. Ti-Cu clad terminal's titanium outer layer will not corrode in acidic copper plating bath, only simple regular surface cleaning required, service life extended to 4–7 years, cutting conductive terminal replacement frequency by over 60%, saving massive labor time and plating solution replacement cost.
Full OEM terminal customization, universal interchangeable with mainstream VCP anode & cathode assemblies Support customized terminal outline shape, hole spacing, titanium cladding thickness, exposed copper conductive contact area according to customer VCP anode frame / flying target CAD drawings. Milled exposed copper surfaces realize copper-copper bolt docking with rectifier busbar, avoid high contact resistance and electric spark hazards caused by titanium-titanium contact, compatible with all mainstream brand VCP anode & cathode assemblies without equipment modification.

Professional Consultation Q&A
Q1: What is the core difference between Titanium Clad Copper Conductive Terminals, solid pure copper terminal, Ti-Cu anode rod/flying target composite parts and MMO coated titanium anode plates?
A1: Titanium Clad Copper Conductive Terminals are independent machined transition conductive lugs for connecting conductive carrier and rectifier busbar; Ti-Cu anode rod/flying target beam are long linear conductive main bodies, different product form and function. Solid pure copper terminal has high conductivity but easy oxidation shedding copper powder to pollute plating liquid, short service life. MMO anode plates are catalytic positive electrolytic electrodes with precious metal oxide coating for oxidation reaction, only matched with Ti-Cu terminals as transition conductive joint, completely different product function. Lead alloy & steel base anode have poor conductivity and metal ion dissolution risk, cannot be used as high-current transition conductive terminals.
Q2: Why choose Ti-Cu clad copper conductive terminal instead of single solid copper or solid titanium terminal?
A2: Single solid titanium terminal has ultra-high resistivity, severe joint voltage drop under large DC current, resulting in inconsistent PCB copper thickness across the whole tank; solid pure copper terminal directly contacts acidic plating liquid splash, rapidly oxidizes to produce copper powder causing massive PCB pinhole defects, requires frequent polishing maintenance and short service life. Ti-Cu composite conductive terminal simultaneously solves both two core defects, greatly reducing full-cycle operation cost of VCP production lines.
Q3: Will titanium-copper composite interface delaminate after long-term plating vibration and large DC current operation?
A3: Our product adopts explosion + hot rolling atomic-level metallurgical bonding, interface shear strength ≥135MPa, passed long-term vibration fatigue test and cold-hot thermal cycle aging test, no delamination risk under standard VCP production working condition; every finished Ti-Cu conductive terminal passes 100% ultrasonic inspection before delivery to eliminate internal interlayer gap hidden danger.
Q4: Can we customize terminal outline, hole spacing and titanium cladding thickness of titanium clad copper conductive terminals?
A4: Full personalized OEM customization supported. Terminal outer shape, bolt hole spacing, outer titanium cladding thickness, exposed copper conductive contact area can be fully adjusted according to customer VCP anode frame & flying target CAD drawing dimensions.
