ASTM B111 C71500 Seamless Copper-Nickel Alloy Tubes High-Efficiency Heat Transfer Saltwater Corrosion Resistance For Marine Industrial Systems

​ASTM B111 C71500 Seamless Copper-Nickel Alloy Tubes – High-Efficiency Heat Transfer & Saltwater Corrosion Resistance for Marine & Industrial Systems

​​Product: ASTM B111 C71500 Seamless Copper-Nickel Alloy Tubes​​

​​Material & Design:​​

• ​​Base Alloy​​: C71500 (CuNi30Mn1Fe), a ​​70/30 copper-nickel alloy​​ with superior corrosion resistance and thermal conductivity.
• ​​Dimensions​​: Outer diameter 10–159mm, wall thickness 1–20mm (customizable).
• ​​Standards​​: Complies with ASTM B111, ASME SB111, and EN 12451 for marine and industrial applications.

Technical Data:​​

Applications:​​

• ​​Marine Systems​​: Condensers, seawater piping, and offshore platforms.
• ​​Industrial Heat Exchangers​​: Oil refineries, chemical processing, and power plants.
• ​​HVAC & Desalination​​: Resists biofouling and scaling in evaporators.

FAQ:​​
​​Q: How does C71500 compare to other copper-nickel alloys like C70600 (90/10)?​​
A: C71500 (70/30) offers ​​higher strength and corrosion resistance​​ than C70600, especially in high-velocity seawater.

​​Q: Can these tubes be welded or bent?​​
A: Yes, they support ​​TIG welding and cold bending​​ without cracking due to excellent ductility (elongation ≥15%).

​​Q: Do you offer anti-fouling coatings?​​
A: Standard tubes have natural anti-fouling properties, but ​​epoxy coatings​​ can be added for enhanced protection.
