T2 Pure Copper Clad Steel Plate – Electrical & Thermal Conductive Grade
Product Overview
Copper clad steel bimetal plate is a high-performance conductive composite material that combines the structural strength and economy of carbon steel with the excellent electrical and thermal conductivity of pure copper. Manufactured by explosion welding or cold roll bonding to achieve metallurgical bonding, this T2 copper grade delivers near-copper conductivity at a fraction of the weight and cost of solid copper. It is the ideal material for electrical bus systems, heat exchangers and current-carrying structural components.
Why Choose CNB Copper Clad Steel?
We manufacture copper clad bimetal products with strict control over copper purity, bonding integrity and dimensional accuracy. Every plate undergoes conductivity testing and bond inspection to guarantee consistent electrical and mechanical performance. We offer various copper thicknesses and base material options to match specific conductivity, strength and cost requirements, with custom slitting and forming services for finished components.
