Copper Nickel Pipes & Tubes are widely recognized for their superior performance in corrosive environments, particularly in marine and industrial applications. At Turnon Alloys, we provide high-quality Copper Nickel Pipes & Tubes engineered for durability, thermal conductivity, and resistance to biofouling. These tubes are essential in systems exposed to seawater and high-pressure fluid transport, offering unmatched strength and longevity.

Copper Nickel Pipes & Tubes are made primarily from copper and nickel, often enhanced with elements like iron and manganese to boost their mechanical properties. These alloys are suitable for a range of demanding environments, from offshore oil rigs to naval ship systems. As reliable Copper Nickel Pipes & Tubes Manufacturers, Turnon Alloys ensures each product meets rigorous quality and international compliance standards. These tubes are available in seamless and welded forms, making them adaptable to various piping needs.
One of the major benefits of Copper Nickel Pipes & Tubes is their resistance to corrosion, especially in saltwater environments. Their resistance to macrofouling reduces maintenance needs and extends operational lifespan. Additionally, they are known for excellent thermal conductivity, low expansion rates, and high ductility. These characteristics allow for easy fabrication, welding, and forming. Turnon Alloys, as established Copper Nickel Pipes & Tubes Suppliers, offers custom lengths, thicknesses, and finishes to suit each project requirement.
Turnon Alloys supplies Copper Nickel Pipes & Tubes that adhere to ASTM B466 and ASME SB111 specifications. We provide popular grades like 90/10 (UNS C70600) and 70/30 (UNS C71500), widely used for condenser tubes, heat exchangers, and marine piping systems. The 90/10 grade offers excellent resistance to seawater and is suitable for general marine engineering, while the 70/30 grade is recommended for applications where higher mechanical strength and better corrosion resistance are essential.
As global Copper Nickel Pipes & Tubes Stockists, Turnon Alloys maintains a robust inventory for immediate dispatch.
