Renowned suppliers of Cu-Ni 70/30 Material, We stock and produce UNS C71500/ NES 780 Hollow and square Pipe
Copper-nickel alloys are some of the best materials used by engineers. This is because of the several amazing properties offered by the material. Firstly, the material has very high ductility, which makes the production of CUPRO NICKEL 70/30 PIPES AND TUBES rather easy. The thermal conductivity of ASTM B466 Cupro Nickel 70/30 Seamless Pipe, is also very good. Yet, if the comparison were between copper and the alloy, there is a decrease in both the thermal as well as the electrical conductivity of the copper nickel 70/30 pipe.
Furthermore, being a very potent alloy, the corrosion resistance of the Copper Nickel 70/30 Seamless Pipe and Tube makes them a valuable addition to industries that require resistance to corrosion. Although, to be more specific, the use of a WERKSTOFF NR. 2.0882 Hexagonal Pipe is more dominant in marine engineering. As an alloy, the content of copper in 70/30 Cu-Ni Hollow Pipe is higher, which makes it very resistant to marine environments. The higher content of copper in the material of Copper Nickel 70/30 / NES 780 makes it resistant to microfouling. However, in comparison to pure copper, the microfouling properties of this alloy tend to be relatively lower.
Moreover, nickel in the alloy is known to increase the tolerance of the UNS C71500 Square Pipe to heat, especially if the pipes are involved in high-temperature environments. In addition to heat exchangers and condensers in marine engineering, the Cu-Ni 70/30 Welded Pipe is well suited to the refrigeration and air conditioning industries.
