Rectangular Copper Bar

CuMetal’s rectangular copper bars are manufactured from premium grade C11000 copper, ensuring excellent electrical and thermal conductivity for demanding electrical applications. Our precision manufacturing process guarantees consistent quality and tight dimensional tolerances.

Product Overview

Rectangular copper bars are the most widely used form of copper busbar in electrical power distribution. Their flat profile provides maximum surface area for heat dissipation and easy connection to electrical components.

Key Advantages

Superior Conductivity

Made from 99.95% pure electrolytic copper (C11000), our rectangular copper bars offer conductivity of ≥97% IACS, ensuring minimal power loss and efficient energy transmission.

Precision Manufacturing

Each bar is manufactured with strict dimensional control, ensuring flatness tolerance of ±0.05mm per 100mm length and edge radius consistent with industry standards.

Surface Treatment Options

Choose from bare copper, tin-plated, silver-plated, or nickel-plated surfaces to meet your specific application requirements for corrosion resistance and contact performance.
