Titanium Clad Copper Drilled Bar

Titanium Clad Copper Drilled Bar is a precision machined titanium copper composite bar featuring customized holes for electrical connection, mounting, or specialized industrial applications.

It combines a high conductivity copper corewith a corrosion resistant titanium outer layer. The drilled or perforated structure allows the finished bar to match specific installation and connection requirements without additional machining by the customer.

We manufacture custom titanium clad copper drilled bars and perforated bars according to drawings, samples, or technical specifications, including customized bar dimensions, titanium cladding thickness, hole diameter, hole position, spacing, and quantity.

Our Titanium Clad Copper Drill Rod (also called Titanium Clad Copper Drilling Bar, Ti-Cu Clad Drill Bar, Titanium Clad Copper Rod for Machining) is manufactured by advanced metallurgical bonding technology, combining the excellent electrical and thermal conductivity of oxygen free copper with the superior corrosion resistance and lightweight strength of titanium. Which is manufactured by explosive bonding, hot rolling, or continuous extrusion, ensuring 100% metallurgical bonding between Titanium and Copper.

Titanium clad copper combines the properties of two metals within one composite structure:

Copper core
High electrical conductivity and efficient current transmission.

Titanium cladding
Excellent resistance to corrosion and aggressive environments.

Precision-machined structure
Customized holes allow the component to be directly integrated into equipment or assemblies.

This combination makes titanium copper composite bars suitable for applications where a conventional copper bar may not provide sufficient corrosion resistance and solid titanium may not provide the required electrical conductivity.
