ASTM B111 C70600 Copper Nickel Alloy Seamless Tube For Condenser
The ASTM B111 C70600 Copper Nickel Seamless Tube are widely used for marine applications due to their excellent resistance to seawater corrosion, low macrofouling rates, and good fabricability.
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.

Why Are Copper Nickel Tubing Used In Heat Exchangers?
Copper nickel tubing is designed with a superior chemical composition allowing them to work well in harsh conditions. These tubes can handle different pressures and temperatures, which is very essential for running heat exchangers. The tubing devices have excellent fatigue strength and mechanical properties, allowing them to withstand the different conditions in this system.
