Copper Round Bar
We manufacture & stock a full range of copper round bar for use in a variety of industries
Copper Round Bar
We manufacture high-quality copper round bar in a wide range of diameters to suit electrical, engineering and manufacturing applications. Copper combines excellent electrical and thermal conductivity with good corrosion resistance. This makes round bar a practical choice for electrical components, machined parts, connectors and general engineering.
Alongside copper round bar, we also supply busbar, flat bar, square bar, wire, sheet and tube. Our in-house capabilities include precision cutting and CNC machining, allowing us to support both standard material requirements and custom copper components.
What is a round bar?
It is a solid cylindrical section supplied in straight lengths and a wide range of diameters. The consistent round profile makes it particularly suitable for turning, machining and producing cylindrical components. Especially where conductivity, durability and dimensional accuracy are important.
At ILF, we manufacture copper in diameters from 3 mm to 8 inches, with several grades available to suit different electrical, engineering and manufacturing requirements.
