Copper Nickel 70/30 Flanges are a type of flange made from a specific alloy known as Cu-Ni 70/30. The chemical composition of this alloy consists of 70% copper (Cu) and 30% nickel (Ni). It may also contain small amounts of other elements like iron (Fe) and manganese (Mn) to enhance its properties. This combination of copper and nickel results in a highly versatile and durable material with unique characteristics.

One of the key features of Copper Nickel 70/30 Flanges is their excellent resistance to corrosion. The presence of nickel in the alloy provides exceptional protection against both seawater and freshwater corrosion, making these flanges ideal for marine and offshore applications. They are commonly used in shipbuilding, desalination plants, and other marine engineering projects where corrosion resistance is critical.

Another advantage of Copper Nickel 70/30 Flanges is their inherent strength and toughness. They possess good mechanical properties and can withstand high-pressure and high-temperature environments, making them suitable for a wide range of industrial applications. Additionally, these flanges have excellent weldability and workability, allowing for easy fabrication and installation.

Copper Nickel 70/30 Flanges typically do not require heat treatment, as their as-cast or as-forged properties are already well-suited for various applications. This saves time and cost during the manufacturing process and ensures the material retains its desirable characteristics.

 Copper Nickel 70/30 Flanges

These flanges find applications in various industries, including petrochemical, chemical processing, power generation, and offshore oil and gas platforms. Their resistance to biofouling and corrosion in seawater also makes them popular choices for heat exchangers, condensers, and other components in marine environments. Moreover, they are used in handling and transporting fluids in harsh conditions due to their outstanding resistance to pitting, crevice corrosion, and stress corrosion cracking.
