Copper/Nickel Alloy Tube (Cu70/Ni30) is a product offered by Goodfellow in its range of high-performance alloy tubing. With 27 variations, these tubes provide excellent corrosion resistance and strength. The copper-nickel alloys are widely used for marine applications as well as in chemical processing, food handling, and power generation where resistance to corrosion is critical. The combination of good mechanical strength and ductility also makes these copper-nickel alloy tubes suitable for applications requiring formed or bent tubing.
