This form of copper nickel tubes produced by WINDO METAL possess excellent resistance to corrosion by sea water as well as high resistance to erosion corrosion and air-impingement attack.

The addition of iron results in 90/10 performing as good as 70/30 in salt water service heat exchangers. These tubes have good strength and ductility at ordinary temperatures and relatively high strength and other mechanical properties at elevated temperatures.

Copper-nickel UNS C70600 has a copper content of not less than 88.6%.

Tabulated below are the mechanical properties of UNS C70600 tubes as a function of heat treatment.

Temper Tensile Str. Yield Str. Elong. Rockwell
B C F 30T
H55 414MPa (60ksi) 393MPa (57ksi) 10% 72 100 70
OS025 303MPa (44ksi) 110MPa (16ksi) 42% 15 65 26

Competitive Advantage:

1. We have more than 12,000 square meters workshop, including 12 finning machines, daily extrusion capacity up to 3,500 meters.

2. The finning machines of Integral Low Fin Tubes are designed and assembled by ourselves and we can offer you finning machines and all the parts of accessories etc…

3. The Integral Low Fins are rolled out of the tube surface to increase the tubes external surface area, without affecting any others dimension.

4. Low Fins are very useful for tight condensers and exhibits high efficiency of heat transfer.

5. Economical solutions of heat exchange problems of media with different heat conduction abilities or different current conditions.

6. High chemical-, thermal- and mechanical resistance, suitable for rough operation conditions.
