Copper Nickel Plate C70600 & C70620
(For Pressure Vessels, Condensers, Heat Exchangers & Desalination Plants)
Copper Nickel Plate C70600 & C70620 possess excellent corrosion resistance property especially in seawater environments. They have high inherent resistance to biofouling and have excellent fabrication and welding properties. The addition of manganese and iron are essential to maintain the good corrosion resistance property of these alloys. They are widely used in marine and offshore industries in typical applications such as pressure vessels, condensers, heat exchangers, boat hulls, ship propellers, flanges and various other marine hardware components, seawater desalination plant, pump impellers for oil refining, evaporators, etc.
