Fortu Tech is an ISO Certified Corporation located in China and specializes in manufacturing Copper Nickel Alloys Tube & Pipe. We have more than 20 years of production experience. Our products are Conflict Free material.
Fortu Tech can customize the Copper Nickel Alloys Tube & Pipe according to your demand. Welcome to contact us if you have any questions or requirements.
Copper Nickel Alloys Tube & Pipe of us meets the standard ASTM B111 C71500.
Copper-nickel alloy (often referred to as "white copper" due to its classic composition ratio) typically contains 60% to 90% copper. The most widely used type is the copper-nickel 70/30 alloy. This alloy is renowned for its outstanding resistance to saltwater corrosion, which makes it an ideal material for manufacturing heat exchangers, condensers, and other low-temperature system pipes and fittings.
Additionally, the copper-nickel 70/30 seamless pipe also has excellent ductility and can withstand high mechanical stress in high-temperature environments, thus finding widespread application in demanding industries such as petroleum refining and cement manufacturing.

1. Marine and Offshore Applications
Copper-Nickel 70/30 tubing is a cornerstone material for marine and offshore applications. The exceptional corrosion resistance of C71500 CuNi alloys 70/30 tubes against saltwater, stress-corrosion cracking, and biofouling makes it the premier choice for shipbuilding, desalination plants, and condenser tubes in coastal power stations.
2. Energy and Chemical Processing
In the energy and chemical sectors, 70%Copper-30%Nickel tubes are indispensable. The robustness of C71500 70/30 tubing allows it to perform reliably in high-temperature, high-pressure environments, handling high-speed and turbulent fluids. This makes 70/30 copper-nickel pipe ideal for heat exchangers, condensers, and processing systems in oil refineries and chemical plants.
3. Low-Temperature and Cryogenic Services
For low-temperature and cryogenic applications, Copper-Nickel 70/30 tubes demonstrate superior performance. The excellent ductility and durability of 70/30 copper-nickel tubing are retained at extremely low temperatures, preventing brittle fracture. This property makes C71500 pipe a trusted material for LNG transport, storage, and handling equipment.
4. Industrial and Manufacturing Uses
The use of Copper-Nickel 70/30 pipe extends to various demanding industrial sectors. C71500 Copper-Nickel 70/30 seamless tubes can withstand high mechanical stress and corrosive environments, making them suitable for the cement industry and other heavy industries. The excellent weldability and formability of 70/30 pipe also facilitate easy fabrication into complex components.
5. Antimicrobial and Specialized Applications
A remarkable advantage of Copper-Nickel 70/30 capillary tubing is its unparalleled antimicrobial property. C71500 tubes can eliminate over 99% of bacteria within two hours. This inherent feature makes 70/30 copper-nickel pipe highly sought-after for hygienic applications in food processing, pharmaceutical industries, and hospital water systems.
In addition to CuNi 70/30 Tube and Pipe , we also produce CuNi 70/30 Sheet & Plate, CuNi 70/30 Ingot, CuNi 70/30 Pellets, CuNi 70/30 Strip, CuNi 70/30 Rod, CuNi 70/30 Wire, CuNi 70/30 Disc, CuNi 70/30 Target, CuNi 70/30 machined parts.
