Cooper Nicekl Alloy Tube For Heat Exchanger ASME SB111-( 90CU10NI)C70600


Copper Nickel C70600 is also known as Copper Nickel 90/10 because it is made up of 10% nickel or as ASTM B111 and ASME SB111. C70600 is known for its moderate strength, weldability, and formability. The inclusion of controlled quantities of iron and manganese also give the 90/10 alloy an extraordinary resistance to general corrosion and stress cracking, as well as to erosion and impingement due to turbulent water containing air bubbles and silt flowing at high velocities.

Properties of Copper-Nickel Tube

Alloy C70600 is normally supplied as redrawn tubing in the annealed condition. The combination of strength and good ductility give excellent formability.

As copper-nickel is softer than steel, it was first feared that fretting might be a problem. Experience has shown this is not the case.


Corrosion Resistance

For many years prior to its application as a brake tubing material, alloy C70600 had been used in ships, power station condensers and hydraulic lines on tankers, and had displayed excellent resistance to saline conditions. Early tests revealed that copper-nickel has almost the same resistance to burst pressure as steel. In testing, however, when exposed to salt spray over 180 days, steel's burst strength decreases significantly. The copper alloy remains consistently resistant.
