Titanium Clad Copper Flat Bar

Titanium Clad Copper Flat Bar (Ti Clad Cu Flat Bar / Titanium Copper Composite Flat Bar / Titanium Clad Copper Bus bar) is a bimetallic composite material made by explosively bonding or roll-bonding pure titanium with high-conductivity copper.

It combines the corrosion resistance of titanium with the excellent electrical and thermal conductivity of copper, making it ideal for harsh electrochemical and power transmission environments.

Titanium Clad Copper Flat Bar is a titanium copper composite product combining the high electrical conductivity of copper with the corrosion resistance of titanium.

The flat bar structure provides a broad, stable contact surface for electrical connections, conductive assemblies, and industrial equipment. The titanium outer layer helps protect the copper core in corrosive or chemically demanding environments while maintaining the conductive advantages of copper.
