China Titanium Clad Copper Suppliers - Custom Sizes, 99.999% Purity, Reliable Factory for Electrolysis & Electroplating
Product Description
Titanium-copper composite material (also known as titanium-clad copper) achieves atomic-level tight bonding between commercial pure titanium and high-conductivity copper through advanced metallurgical processes such as explosive bonding, roll bonding, or explosive-roll bonding. This bimetallic composite not only retains the excellent corrosion resistance of titanium but also possesses the superior electrical and thermal conductivity of copper, along with reliable structural strength. It can effectively replace pure titanium, pure copper, and precious metal alloys, easily handling complex working conditions such as strong corrosion, high current, and high temperature.
