Advantages of ASME SB111 C71500 Copper Nickel Alloy Seamless Tubes for Marine Condenser Applications

1.​​Superior Corrosion Resistance​​

With 29-33% nickel content, C71500 alloy offers exceptional resistance to seawater corrosion, pitting, and biofouling, ensuring long-term durability in marine environments.

​​2.High Mechanical Strength​​

​​Annealed (O61)​​: Tensile strength ≥52 ksi, yield strength ≥18 ksi.
​​Drawn & Stress-Relieved (HR50)​​: Tensile strength ≥72 ksi, yield strength ≥50 ksi—ideal for high-pressure condenser systems.

3.​​Excellent Ductility​​

Elongation ≥15% (thicker walls) to 12% (thin walls) post cold-working, enabling complex installations without cracking.

​​4.Thermal Stability​​

Maintains structural integrity under fluctuating temperatures, critical for condensers exposed to steam and seawater.
