The core advantage: a run made from one coil has no joints in it at all — every fitting that does not exist is a leak point that cannot happen.

Why buy copper coils from us

  • Soft annealed temper — bends by hand, accepts flares without splitting.
  • 45–50% elongation — above the 40% minimum standard; fine 0.025 mm grain.
  • C1220T at 99.96% purity — phosphorus deoxidised, braze-ready.
  • EN 10204 3.1 certificate — purity, phosphorus, tensile, elongation, grain, bore clearness.
  • The straight lengths toocopper pipes 6–54 mm from the same stock.

Overview

Soft vs hard — and coils vs straight lengths

Why the soft temper

Annealing gives 45–50% elongation (against the 40% minimum standard) and a fine 0.025 mm grain structure — the coil bends smoothly without wrinkling, accepts flares without splitting, and solders/brazes well. Hard copper (straight pipe) needs reheating to bend.

When the coil wins

Refrigeration runs and tight routing: one 15 metre coil = one run with no fittings at any change of direction. For rigid risers and runs above 15 mm, straight copper pipe is the better choice.


Joining

Three ways to join

Capillary fittings

Soldered or brazed — brazing preferred for AC and refrigeration, service up to 176 °C.

Flare fittings

The soft temper accepts flares without splitting — the refrigerant-line standard.

Compression fittings

Make and break without heat — for service and instrument work.

Soldering done right: measure the length · clean coil & fitting with abrasive and apply flux · heat until the solder melts fully into the capillary gap · cool until solid · clean the excess. Avoid melting excessive solder into the gap. Maintenance: rinse with soap and water (a dash of vinegar & distilled water) to prevent clogging — e.g. in AC systems.

FAQ

Frequently asked questions

What is a copper pancake coil?

Seamless copper tube wound flat in soft annealed temper — it bends by hand, accepts flares without splitting, and a run made from one coil has no joints in it at all.

What is the difference between soft and hard copper?

Soft (annealed, coiled): flexible, reshapeable during installation, right for flares & coolant lines. Hard (straight pipe): water lines, difficult to bend without reheating.

What is the composition of C1220T?

Copper min 99.90% (actual 99.96%), phosphorus 0.015–0.040% (actual 0.024–0.028%).

Why does phosphorus deoxidisation matter?

It removes the oxygen, so welding and brazing improve — with no hydrogen embrittlement risk when heated.

How is it joined?

Capillary (solder/braze), flare and compression fittings. For AC and refrigeration, braze is preferred — service to 176 °C.

Solder or braze?

Braze for refrigerant lines and higher temperatures; solder is enough for water and light service.

When coils, when straight lengths?

Coils: refrigeration & tight routing — no joints. Straight: rigid risers and runs above 15 mm.

What is the standard coil length?

15 metres per coil.

Suitable for air conditioning and refrigerant?

Yes — that is the primary use. The annealed 45–50% elongation and fine 0.025 mm grain make it bend smoothly without wrinkling.

Are they in stock for Indonesia?

Yes — 6–15 mm OD (1/4″–3/4″) in our regional warehouses in Singapore and Malaysia; out within 24 hours, quotes within 2 working hours.
