Copper-nickel 70/30 tubes, also known as CuNi 70/30, are highly valued in various industries due to their exceptional properties and versatility. This alloy, composed of 70% copper and 30% nickel, offers a unique blend of characteristics that make it ideal for numerous applications. The 70/30 copper-nickel alloy is excellent at preventing corrosion, especially in seawater conditions. Because of its ability to withstand corrosion from seawater, it is a favored material for use in offshore constructions and shipbuilding. The alloy strengthens its resistance to adverse environmental conditions by forming a protective oxide layer.
Good tensile strength and resilience to wear and tear are displayed by copper-nickel 70/30. Because of this, it can be used in high-stress situations where durability is essential. The alloy's ability to retain its mechanical qualities at high temperatures guarantees long-term functionality.
The thermal conductivity of 70/30 copper-nickel is noteworthy, even though it isn't as high as that of pure copper, which makes it helpful in heat exchange applications. CuNi 70/30 is frequently utilized in maritime engineering, including ship hulls, desalination facilities, and offshore platforms, because of its resistance to corrosion.
