Titanium Clad Copper Bar: Conductivity and Corrosion Resistance Combined
Introduction
Titanium Clad Copper Bar is a composite metal bar that combines a copper core for high electrical conductivity with an outer titanium layer for corrosion resistance. It is mainly used in electrolysis, electroplating, hydrometallurgy, chlor-alkali systems, copper foil production, wastewater treatment and electrochemical equipment where the material must carry current efficiently while resisting acid, chloride or oxidizing environments. To specify it correctly, buyers should confirm copper grade, titanium grade, cladding thickness, bar size, bonding method, electrical requirement, surface condition, inspection standard, certificate requirement and final application.
The main advantage of titanium clad copper bar is material efficiency. Pure titanium has excellent corrosion resistance but relatively low electrical conductivity, while pure copper has excellent conductivity but poor corrosion resistance in many chemical environments. By combining both metals, titanium clad copper bar provides a practical solution for conductive anode hanger bars, bus bars, electrode connectors and electrochemical current-carrying components.
SAKY ALLOY supplies titanium clad copper bars, titanium clad copper rods, titanium clad copper bus bars, titanium anodes, titanium plates, titanium bars, titanium tubes and customized titanium alloy products with material certificates, dimensional inspection, bonding quality inspection, export packaging and delivery support for global industrial customers.
What Is Titanium Clad Copper Bar?
Titanium clad copper bar is a bimetallic composite product made by metallurgically or mechanically bonding titanium to a copper core. The copper core provides the main current-carrying function, while the titanium outer layer protects the bar from corrosive media. In many electrochemical systems, the titanium surface is exposed to the working environment, while the copper core improves conductivity and reduces voltage loss.
Common titanium materials used for the outer layer include Grade 1 and Grade 2 commercially pure titanium. Common copper core materials include T2 copper, C11000 electrolytic tough pitch copper and other high-conductivity copper grades. The final performance depends on cladding thickness, bonding quality, copper purity, titanium surface quality and fabrication accuracy.

Chemical Composition
Titanium clad copper bar contains two functional materials: the titanium cladding layer and the copper core. The titanium layer is selected for corrosion resistance, especially in chloride-containing, acidic and electrochemical environments. The copper core is selected for high electrical conductivity. Both materials should be verified by material certificate and chemical composition data.
| Material Layer | Common Grade | Main Elements | Typical Chemical Requirement | Function In Composite Bar |
|---|---|---|---|---|
| Titanium Outer Layer | Grade 1 / UNS R50250 | Ti, O, Fe, C, N, H | Commercially pure titanium with very low interstitial elements. | Excellent corrosion resistance and good ductility. |
| Titanium Outer Layer | Grade 2 / UNS R50400 | Ti, O, Fe, C, N, H | Commercially pure titanium with higher strength than Grade 1. | Corrosion protection with better mechanical strength. |

Final chemical composition should be confirmed according to the applicable titanium and copper material standards, purchase order and actual Material Test Certificate. For electrochemical use, copper purity and titanium surface quality are both important.
Mechanical And Electrical Properties
Titanium clad copper bar is not selected only for tensile strength. Its most important performance is the combined function of copper conductivity and titanium corrosion resistance. Buyers should review mechanical properties, cladding thickness, bonding strength, straightness, dimensional tolerance and electrical conductivity requirement according to the final service condition.
| Performance Item | Titanium Layer | Copper Core | Composite Bar Result | Buyer Check |
|---|---|---|---|---|
| Electrical Conductivity | Low compared with copper | Very high conductivity | Good current carrying performance with corrosion-resistant surface. | Confirm current load, voltage drop and copper core size. |

| Bonding Quality | Must remain attached to copper core | Must provide stable conductive base | Good bonding avoids delamination during service. | Request bonding inspection or sample approval if required. |
Applicable Standards And Certificates
Titanium clad copper bar is often produced according to customer drawings and technical agreements because it is a functional composite product. Buyers should specify titanium and copper base material standards separately, and also define composite requirements such as cladding thickness, bonding quality, dimensions, surface finish and inspection method.
| Material / Product | Common Grade | UNS / Designation | Typical Standard Reference | Certificate Check |
|---|---|---|---|---|
| Titanium Layer | Titanium Grade 1 | UNS R50250 | ASTM B265 / ASTM B348 depending on product form | Chemical composition, mechanical properties and heat number. |
| Titanium Layer | Titanium Grade 2 | UNS R50400 | ASTM B265 / ASTM B348 depending on product form | Strength, chemical composition and corrosion application suitability. |

For project procurement, certificates may include titanium MTC, copper MTC, composite product inspection report, dimension report, bonding quality inspection, electrical performance record and third-party inspection report. EN 10204 3.1 certificate support can be discussed according to the material and order requirements.
Quality Testing And Material Traceability
Quality control for titanium clad copper bar should focus on both raw material and composite performance. The titanium and copper materials must meet grade requirements, while the finished composite bar must meet bonding, dimensional and surface requirements. Heat number control, batch traceability and anti-fake material control are important when the bars are used in electrochemical plants and long-term industrial systems.
| Inspection Item | Purpose | Buyer Check |
|---|---|---|
| Raw Material MTC | Confirms titanium and copper chemical composition and grade. | Check titanium grade, copper grade, heat number and certificate data. |

How To Specify Titanium Clad Copper Bar For RFQ
A complete RFQ helps the supplier confirm the correct structure, production method and inspection scope. Because titanium clad copper bar is often customized, buyers should provide drawings whenever possible. Important details include titanium grade, copper grade, overall size, titanium layer thickness, length, quantity, hole size, machining requirement, current load, working medium and certificate requirement.
| RFQ Field | Example | Why It Matters |
|---|---|---|
| Titanium Grade | Titanium Grade 1 or Grade 2 | Determines corrosion resistance and mechanical behavior of the outer layer. |
| Copper Core | T2 Copper / C11000 Copper | Controls electrical conductivity and current carrying capacity. |
| Size | 30 mm × 50 mm × 3000 mm, or as drawing | Affects conductivity, load capacity and installation design. |
| Titanium Layer Thickness | Customized, such as 1 mm, 2 mm or project requirement | Determines corrosion allowance and service life. |
| Processing Requirement | Cutting, drilling, slotting, bending, machining | Ensures the bar fits actual installation and equipment design. |
| Working Environment | Acid, chloride, electrolysis bath, plating solution | Helps confirm titanium grade, cladding thickness and service suitability. |
| Certificates | MTC, dimension report, bonding inspection, third-party inspection | Supports project approval and traceability. |
Why Choose Titanium Clad Copper Bar?
Titanium clad copper bar is chosen because it solves two problems at the same time: copper provides efficient current conduction, while titanium protects the bar from corrosion. This makes it especially valuable for electrochemical equipment where pure copper may corrode quickly and pure titanium may cause higher electrical resistance.
For industrial buyers, the key purchasing value is not only the material combination, but also the reliability of the bonding layer, dimensional accuracy, certificate support and export packing. A well-specified titanium clad copper bar can reduce energy loss, improve service life and lower maintenance frequency in demanding electrochemical systems.
