Cupro Nickel 70/30 flanges are essential components used in various industrial applications requiring excellent corrosion resistance, high strength, and good thermal stability. These flanges are made from a specific alloy known as Cupro Nickel 70/30, composed of 70% copper and 30% nickel, with trace amounts of other elements.

Cupro Nickel 70/30 is well-known for being highly resistant to corrosion. It can handle saltwater and brackish water, making it great for use in marine conditions. It also prevents the build-up of organisms and marine growth on surfaces, extending its usability in aquatic systems.

Cupro Nickel 70/30 has strength, making it excellent for situations that demand high durability and structural dependability. It possesses impressive mechanical properties - featuring a great combination of strength and flexibility - that let it handle extreme pressure and temperature. This makes it ideal for flanges utilised in pipelines, heat exchangers, and other important systems.

The strength of Cupro Nickel 70/30 makes it suitable for jobs that need tougher and more sound resistance. Its mechanical qualities are distinguished by an amazing combination of tensile resilience and malleability, permitting it to endure intensely high pressure and temperature. This makes it ideal for flanges employed in pipelines, heat exchangers and other key structures.

Furthermore, Cupro Nickel 70/30 flanges have excellent resistance to biofouling and microbiologically influenced corrosion (MIC). Biofouling refers to the accumulation of bacteria, algae, and other microorganisms on surfaces, which can degrade equipment performance and increase maintenance requirements. Cupro Nickel 70/30's inherent resistance to biofouling helps prevent the formation of these organisms, reducing the risk of clogging or blockages in systems such as seawater cooling systems or offshore structures.
