Cupro Nickel vs Copper Tubes
Seawater Corrosion
- Cu-Ni resists seawater attack better
- Plain copper wears faster in flowing seawater
- Choose Cu-Ni for marine service
Heat Conduction
- Copper conducts heat better
- Cu-Ni transfers enough for condensers
- Match the tube to the duty
Cost & Life
- Cu-Ni costs more upfront
- Longer life cuts replacement cost
- Nickel content drives the price
Cupro Nickel Tube Price Per Kg
Cupro Nickel Tubes are priced per kg, moving with copper and nickel markets.
