Copper Coil

Cu-ETP and Cu-DHP copper coil. Thicknesses from 0.05 mm to 1 mm and widths up to 1000 mm; narrower widths slit to order are supplied as Slit Copper Strip.

Grades 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.

Strip standards: EN 1652 · electrical purposes: EN 13599

Cu-DHP · CW024A

Cu-DHP

Phosphorus-deoxidised copper (min. 99.90% Cu, 0.015–0.040% P). Being oxygen-free, it resists hydrogen embrittlement during welding and brazing and is very well suited to gas-shielded arc welding, brazing and soldering. The residual phosphorus lowers conductivity (min. 46 MS/m, about 79% IACS, in the soft condition); it is preferred for tube, plumbing, heat exchangers and forming work.

Frequently asked questions

What are the designations for Cu-ETP and Cu-DHP?

Cu-ETP: EN CW004A, DIN 2.0060, UNS C11000, BS C101. Cu-DHP: EN CW024A, DIN 2.0090, UNS C12200, BS C106. 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 grade, temper, size (thickness × width), total weight in kg and delivery location. If you fill in the calculator above, these details are added to the WhatsApp message automatically.
