Copper Nickel 70/30
This alloy has all the characteristics of CuNi 90/10, but also offers excellent corrosion resistance in high velocity sea water. Also the operation temperature is much higher than of CuNi 90/10. Can assure a long service life and reliability.
Weight Formula: Average wall: (OD-WT) * WT * 0.0284 = Kg/m (all sizes in mm)
