1. Material Data

Property Value
Cu (min) 99.90%
P 0.004-0.012% (low residual - DLP)
Conductivity ~85-90% IACS
Thermal conductivity ~340-360 W/m·K
Tensile (annealed) 200-260 MPa

DLP = phosphorus-deoxidized, low residual phosphorus. Deoxidation removes oxygen, preventing hydrogen embrittlement during brazing; the low phosphorus keeps conductivity high while improving weldability.

 

2. C12000 vs C12200

C12000 (DLP): lower phosphorus, higher conductivity - industrial fabrication, heat exchangers, HVAC;

C12200 (DHP): higher phosphorus (0.015-0.040%), best corrosion resistance in potable water - plumbing per ASTM B88;

Both are oxygen-free and weldable; choose by conductivity vs corrosion requirement.

 

3. Pancake Coil Form

Soft-annealed (O61) tube coiled flat - compact, low-cost transport;

Straightened and cut on site; ideal for long-run heat-exchanger fabrication;

Clean bore (degreased, capped ends) for refrigerant/water service;

Typical: OD 6.35-25.4 mm (1/4"-1"), wall 0.6-1.5 mm, coil length 10-100 m, coil OD 400-1200 mm.

 

4. Applications

Shell-and-tube and finned heat exchangers, condensers and evaporators, solar water heaters, oil coolers, refrigeration and HVAC circuits, and general heat-transfer coils where weldable high-conductivity copper is required.

 

5. Ordering

Specify: standard (B68/B75/B280 or EN 12735), grade C12000, OD × wall, coil length and coil OD, temper (O), cleanliness class, and EN 10204 3.1 certificate with phosphorus and conductivity analysis.

Application

Copper plates are mainly used in electrical conductivity, heat conduction, and corrosion-resistant equipment. For instance, they

are applied in wires, cables, conductive screws, blasting detonators, evaporators for chemical industries, storage containers, and

various pipelines, etc. They can also be used as force-bearing parts for various deep drawing and bending manufacturing processes,

such as pins, rivets, washers, nuts, conduits, pressure gauges, screens, and radiator parts, etc.
