Copper Round Bar – UK Manufacturer, Supplier & Stockholder
We manufacture & stock a full range of copper round bar for use in a variety of industries
Copper Round Bar
As a UK copper round bar manufacturer and stockholder, ILF Products produces round bar in diameters from 3 mm to 8 inches for electrical and engineering applications. Copper combines excellent electrical and thermal conductivity with good corrosion resistance. Consequently, round bar suits electrical components, machined parts, connectors and general engineering.
Alongside round bar we supply busbar, flat bar, square bar, wire, sheet and tube. In-house precision cutting and CNC machining let us support both standard material requirements and custom copper components.
What is a round bar?
A solid cylindrical section, round bar is supplied in straight lengths. ILF Products makes it in diameters from 3 mm to 8 inches. Because the profile is consistent along its full length, it suits turning, machining and the production of cylindrical components, especially where conductivity and dimensional accuracy matter.
We manufacture it at our Cannock, Staffordshire works, with several grades available to suit different electrical, engineering and manufacturing requirements.

Key Benefits of Copper Round Bar
The cylindrical profile gives engineers a versatile starting material for electrical, engineering and manufacturing applications. Specifically, a solid round section machines and turns well. That suits components which need reliable electrical or thermal conductivity, with dimensional consistency to match.
2
Excellent Conductivity
Copper’s defining property is its excellent electrical and thermal conductivity. For that reason, round bar suits electrical components, connectors, switchgear parts, grounding components and any other application where efficient conductivity matters.
1
Strong, Solid Profile
A solid cylindrical section gives engineers a consistent material profile to machine into pins, bushes, connectors and other round components. Its uniform shape also makes it well suited to turning and precision manufacturing.
3
Easy to Machine and Fabricate
Copper round bar can be cut, drilled and machined to suit your requirements. Furthermore, the choice of grade gives you options where machinability or conductivity takes priority.
4
Multiple Industry Uses
Manufacturers rely on copper round bar across electrical engineering, power distribution, automotive, transport, general engineering and precision manufacturing.
