Flat Copper Bar

CuMetal’s flat copper bars are thin, flexible copper strips designed for applications requiring formability and high conductivity. Available in various thicknesses and widths to suit diverse electrical applications.

Product Overview

Flat copper bars (also known as copper strips or flat busbar) are thinner than standard rectangular busbar, making them ideal for jumpers, connectors, grounding straps, and applications where flexibility is required.

Key Features

Excellent Formability

Soft temper flat copper bars can be easily bent, formed, and shaped to fit complex configurations without cracking or compromising conductivity.

Uniform Dimensions

Precision rolling ensures consistent thickness and width throughout the entire length, ensuring reliable performance in your applications.

Clean, Smooth Edges

Deburred and smoothed edges for safe handling and improved electrical performance.
