Cupro Nickel 70/30 is a popular engineering material with outstanding corrosion resistance and mechanical properties. It is an alloy primarily composed of copper and nickel with the addition of a few other elements like iron and manganese. The alloy is extensively used in various industries, such as marine, oil and gas, aerospace, and chemical.
Cupro Nickel 70/30 Flanges Features
Cupro Nickel 70/30 Flanges are known for their outstanding features, like excellent thermal conductivity, high ductility, and superb weldability. It also features excellent workability, machinability, and resistance to stress corrosion cracking. Additionally, the flat-bottomed symmetric design of the flanges ensures ease of installation and improved performance. The flanges are available in various sizes and designs that cater to diverse industrial applications, such as piping systems for seawater environments, chemical processing plants, heat exchangers, and desalination plants.

Cupro Nickel 70/30 Flanges Corrosion Resistance
Cupro Nickel 70/30 flanges offer exceptional resistance to corrosion in seawater, brine, and other corrosive media. Its strong resistance to biofouling and enhanced resistance to crevice corrosion and impingement attacks make it an ideal choice for marine applications. Raw seawater and marine environments containing hydrocarbons, chlorides, and sulfides are aggressive environments that can quickly deteriorate metallic materials. However, Cupro Nickel 70/30 flanges offer high resistance to these aggressive environments and provide extended service life.
Cupro Nickel 70/30 Flanges Chemical Composition
Cupro Nickel 70/30 is an alloy of 70% copper, 30% nickel, and a few trace elements like iron, manganese, and silicon. The alloy's chemical composition significantly influences its microstructure and, in turn, its mechanical and physical properties. The nickel content of Cupro Nickel 70/30 alloy enhances its corrosion resistance, while the copper content improves its strength and resistance to erosion. The trace elements also play a crucial role in modifying the alloy's properties and behaviour in specific applications.
Cupro Nickel 70/30 Flanges Physical & Mechanical Properties
The key physical properties of Cupro Nickel 70/30 flanges include excellent thermal conductivity, electric conductivity, and high flexibility. It features a low thermal expansion coefficient, resulting in better dimensional stability under thermal stress. The alloy is also easy to fabricate, weld, and machine, resulting in better workability and reduced lead times. The key mechanical properties of the alloy are tensile strength, yield strength, elongation, and hardness. The alloy also features excellent resistance to stress corrosion cracking, fatigue, and creep.
