Copper Tube in Coils (Pancake Coils)

Annealed (soft) Cu-DHP copper tube in coils. Easy to bend on site in air conditioning and refrigeration installations; supplied in 50 m or 100 m coils.

Grade and sizes

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

How do I convert inch sizes to millimetres?

1″ = 25.4 mm. For example, 1/4″ = 6.35 mm, 3/8″ = 9.52 mm, 1/2″ = 12.7 mm, 5/8″ = 15.88 mm, 3/4″ = 19.05 mm.

What are the designations for Cu-DHP?

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 size (outside diameter × wall thickness × length), quantity and delivery location. If you fill in the calculator above, these details are added to the WhatsApp message automatically.
