Copper Flat Bar (Busbar)

Flat bar (busbar) in electrolytic tough pitch copper (Cu-ETP). For switchboards, busbar systems and earthing; we cut it to the length you need.

Grade and sizes

Cu-ETP · CW004A

Cu-ETP

Electrolytic tough pitch copper (min. 99.90% Cu). In the soft condition its electrical conductivity is at least 58 MS/m (100% IACS) and its thermal conductivity about 390 W/mK; it is the standard material for busbars, earthing, switchgear and electrical connection parts. Because it contains up to 0.04% oxygen it can embrittle when heated in a hydrogen-bearing atmosphere, so Cu-DHP is preferred for welded and brazed work.

Frequently asked questions

Which copper should be used for busbars?

High-conductivity Cu-ETP (CW004A) is the grade used for busbars and electrical conductors. All our flat bars are Cu-ETP.

What are the designations for Cu-ETP?

Cu-ETP: EN CW004A, DIN 2.0060, UNS C11000, BS C101. Any of these designations can be used in your enquiry; we will match the correct material.

Why can the invoiced weight differ from the calculated weight?

The calculator gives the theoretical weight. The actual weight varies with dimensional tolerances and cutting allowance; we invoice on the actual weight as weighed.

What information should I send for a quote?

We only need the size (thickness × width × length), quantity and delivery location. If you fill in the calculator above, these details are added to the WhatsApp message automatically.
