CuNi 70/30 Tubes is a copper-nickel alloy that is widely used in industries due to its excellent resistance to erosion, corrosion and pitting corrosion and oxidation resistance that is combined with good strength, workability, and weldability. The alloy is mostly used in the marine sector and offshore industries also. The alloy consists of 70% of copper and 30% of nickel. Furthermore, it is popular for its erosion and corrosion resistance. Its corrosion resistance property gets improved due to the velocity of the water as well as polluted seawater.
In the annealed condition, the Cu-Ni alloy tube offers moderate strength which enables it to use in various demanding applications. In addition to this, the copper-nickel alloy displays resistance biofouling. It reacts well in the fabrication process and is enthusiastically cold and hot worked. However, Cupro Nickel 70/30 Seamless Tubes are considered best for their excellent features and mechanical properties. These tubes are available in different specifications, shapes, sizes, and forms as per the demand of customers.

From where to buy:
You can buy the high and superior quality of Cu-Ni 70/30 Welded Tubes from Solitaire Overseas; it is the leading manufacturing and exporting company. The manufacturers while making these tubes make sure that all the material they are using is of high quality and there is no defected material used for manufacturing these tubes. Every material manufacturers use for manufacturing is tested so that they can provide their best in the respective areas of usage.
Besides the high quality of raw material, high-tech technology and machines are used making high quality of tubes. However, if we talk about the properties and feature these tubes display various crucial features like tensile strength, corrosion resistance, oxidation resistance, erosion resistance, durability, weldability, formability, and workability. All these features make Cu-Ni tubes even more demanding and popular for different industrial applications.
Testing and packaging
To check how these CuNi 70/30 Tubes, are made and quality, various tests, and inspections are performed. The entire testing process is conducted by the manufacturers which take place under the supervision and in the regulation of experts so that no defected tube is made ready for the delivery. The tests mainly include third party inspection as they provide quality inspection documents and other documentation, proving products quality and durability. At last, these CuNi 70/30 Tubes are packed and delivered to their relevant customers.
