Material Grade:

Advantage of CuNi Tubes:

• Simple alloying system with good weldability
• Excellent ductility and toughness
• Outstanding erosion corrosion performance
• Resistant to uniform and localised corrosion
• No effect of ambient seawater temperatures
• No effect of seawater chlorination
• Resistant to biofouling
• Resistant to stress-corrosion cracking
• Low maintenance costs
• A lot of design experience

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.
