Product Introduction
Our titanium clad copper irregular parts adopt high-energy explosion welding + multi-pass hot rolling metallurgical composite forming process. Outer seamless 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 covers all custom non-standard special-shaped conductive structural parts on anode & cathode sides of automatic VCP vertical continuous PCB copper plating lines, including irregular transition lugs, offset conductive brackets, bent suspension supports, stepped connection blocks, asymmetric base plates, special-shaped anode hanging seats, flying target eccentric conductive joints and other one-off OEM machined components. The internal high-conductivity OFHC copper core minimizes large DC voltage drop at complex irregular connection positions, guarantees uniform current transmission of non-standard equipment structures; seamless Grade2 titanium outer layer directly contacts acidic sulfuric copper plating liquid splash and immersion environment, completely isolates copper core from corrosive electrolyte, fundamentally solving oxidation, copper powder shedding and bath liquid pollution defects of solid pure copper irregular machined parts.
Differentiation vs other standard Ti-Cu & single-metal products:
● Standard Ti-Cu bar/rod/plate/terminal: regular linear or simple flat standard parts; irregular parts are one-off CNC machined complex special-shaped customized components according to unique VCP equipment drawings;
● Solid pure copper irregular parts: high conductivity but rapid acid oxidation, copper powder leads to PCB pinhole defects, short service life and frequent maintenance;
● Solid pure titanium irregular parts: ultra-high resistivity, severe voltage drop at complex joints causing uneven PCB copper thickness;
● MMO coated titanium anode plate: catalytic electrolytic electrode, only matched with Ti-Cu irregular conductive parts as support & transition;
● Lead alloy / steel base anode: poor conductivity, continuous metal ion dissolution, cannot be used as high-current irregular conductive structural parts. Support full 5-axis CNC precision machining: milling, drilling, tapping, bending, grooving, offset step forming, full edge stripping titanium to expose pure copper core for copper-to-copper low-resistance bolt docking, eliminating titanium-titanium contact electric spark and high contact resistance hidden risks. Stable service life reaches 4–7 years under 24h non-stop high-current VCP plating production, far exceeding solid copper irregular fittings. 100% fully customized per customer unique equipment CAD drawings: arbitrary outline, thickness, titanium cladding thickness, exposed copper area, hole layout and bending angle without fixed mold limitation. We have over 10 years experience custom machining Ti-Cu irregular composite parts 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 for complex irregular structures Internal OFHC copper core retains top industrial electrical conductivity, eliminates voltage drop at complex offset, bent and stepped irregular connection positions under heavy DC load, ensures consistent current output of special-shaped equipment structures, 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 irregular part oxidation & copper powder shedding, drastically reduces PCB reject rate caused by pinholes and surface blemishes.
Explosion hot rolling integral bonding, tight atomic 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 irregular part passes 100% ultrasonic flaw detection before delivery to eliminate hidden interlayer gaps.
Far longer service life & sharply reduced irregular fitting maintenance frequency vs solid copper custom parts Solid pure copper irregular machined fittings need disassembly, polishing and re-passivation every 3–6 months, and will be severely corroded & thinned after only 2–3 years requiring full equipment frame replacement. Ti-Cu clad irregular parts' 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 non-standard conductive component replacement frequency by over 60%, saving massive labor time and plating solution replacement cost.

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 customized anode & cathode assemblies without secondary equipment modification.

Professional Consultation Q&A
Q1: What is the core difference between Titanium Clad Copper Irregular Parts, standard Ti-Cu bar/rod/plate/terminal, solid pure copper custom irregular fittings and MMO coated titanium anode plates?
A1: Single solid titanium irregular part has ultra-high resistivity, severe voltage drop at complex bent/stepped joints under large DC current, resulting in inconsistent PCB copper thickness across the whole tank; solid pure copper irregular fitting 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 irregular parts simultaneously solves both two core defects, greatly reducing full-cycle operation cost of customized VCP production lines.
Q2: Why choose Ti-Cu clad copper irregular custom parts instead of single solid copper or solid titanium CNC machined special-shaped fittings?
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 irregular custom part passes 100% ultrasonic inspection before delivery to eliminate internal interlayer gap hidden danger.
Q4: Can we fully customize arbitrary irregular outline, bending angle, titanium cladding thickness of titanium clad copper irregular parts?
A4: Full personalized one-off OEM customization supported. Arbitrary irregular outer profile, bending angle, stepped height, hole spacing, outer titanium cladding thickness, partial/full exposed copper conductive contact area can be 100% adjusted and machined fully per customer VCP anode/flying target CAD drawing dimensions, no standard mold restriction.
