C71500 Copper Nickel Size & Price PDF
Products Description
The C71500 copper-nickel alloy series is primarily composed of copper and nickel, with trace amounts of other elements to optimize performance. This alloy typically exhibits a silvery-white metallic luster and possesses good mechanical strength and corrosion resistance. In terms of heat transfer, C71500 has a moderate thermal conductivity, effectively transferring heat, while its resistance to seawater and acid/alkali corrosion makes it suitable for various complex environments. This material maintains structural stability at high temperatures and is not prone to deformation or failure.

Application areas of ASME SB111 C71500
ASME SB111 C71500 heat exchanger tubes are widely used in industrial equipment requiring efficient heat exchange. For example, in shipbuilding, they are commonly used in cooling systems and engine heat exchangers to help maintain the normal operating temperature of equipment. In the chemical industry, C71500 tubes can be used in reactors or distillation units to transfer heat to facilitate chemical processes. Power generation and food processing also rely on this material to build reliable heat exchange networks. Its applicability stems primarily from its compatibility with a variety of media, such as fresh water, seawater, or chemical solutions.
FAQ
Q: What are the key properties of C71500?
A: The key properties of C71500 include superior resistance to seawater corrosion and biofouling, excellent resistance to stress-corrosion cracking, good ductility and strength, and high thermal conductivity.
Q: In what applications is C71500 commonly used?
A: C71500 is widely used in marine engineering for condenser and heat exchanger tubes, piping systems for seawater, desalination plants, offshore oil and gas platforms, and shipbuilding.
Q: How does C71500 perform in seawater service?
A: C71500 performs exceptionally well in seawater. It has a very low corrosion rate, high resistance to impingement and erosion corrosion, and naturally inhibits the attachment of marine organisms (biofouling).
