We offer These Copper Nickel 70/30 Fasteners as per DIN, ISO, JIS or ANSI Standard.
Corrosion Resistance: The Copper Nickel 70/30 alloy is highly resistant to seawater corrosion, making it an ideal surface for marine applications. This resistance is due to forming a protective oxide layer on its surface, increasing its longevity and durability in harsh environments.
Low biofouling: Resistance to biofouling (accumulation of microorganisms, plants, algae, or animals in wet environments) makes it especially suitable for marine products and equipment that are constantly exposed to water
Mechanical Strength: Copper Nickel 70/30 provides excellent mechanical strength and flexibility, allowing fasteners made of this alloy to withstand high stresses and strains without rusting or breaking
Thermal stability: This alloy retains its mechanical properties over a wide temperature range, making it suitable for applications where temperature changes are frequent, such as marine and offshore installations
Easy to manufacture: Copper Nickel 70/30 is easily manufactured in a variety of shapes and sizes, making it versatile for bonding applications. It can also be machined, welded, and fabricated with great ease.
Copper Nickel 70/30 fasteners manufactured by reputable companies find widespread industrial use across various sectors. These fasteners, crafted from Copper Nickel alloy, are prized for their exceptional corrosion resistance, making them a preferred choice for applications exposed to harsh environments, especially marine and offshore settings. Industries such as shipbuilding, offshore oil and gas, chemical processing, power generation, and desalination plants rely on Copper Nickel fasteners for their reliability and longevity.
Marine Applications: Copper Nickel 70/30 is highly resistant to seawater corrosion. It is an excellent choice for fasteners in marine environments where these binders are used on ship production, offshore platforms and desalination plants.
Piping: For applications where corrosion resistance and durability are required, such as chemical plants and power plants, pipes using 70/30 copper nickel fasteners are used to help ensure watertight and reliable connections over time.
Heat Exchanger: Copper Nickel 70/30 is known for its excellent heat conductivity and biocorrosion resistance, making it suitable for heat exchangers in a variety of industries including HVAC systems, refrigeration units and industrial heat transfer units, including the equipment
Desalination equipment: Due to its resistance to corrosion and biofouling, copper-nickel 70/30 fasteners are commonly used in desalination plants for seawater intake and processing equipment, including pumps, valves and filtration systems
Oil and Gas Industry: In offshore oil and gas exploration and production, copper-nickel 70/30 fasteners used on critical components such as valves, flanges and connectors to ensure reliability and durability occur where equipment is exposed to harsh marine environments
Copper nickel 70/30 fasteners are manufactured through processes such as hot forging, cold forming, or machining. Raw materials of copper and nickel, along with small additives, are shaped into fastener components using techniques like casting, extrusion, or machining, followed by heat treatment and surface finishing for desired properties and quality.
Copper nickel 70/30 fasteners are generally not recommended for hygienic and sanitary applications due to potential copper leaching and corrosion risks in contact with certain substances. Stainless steel or other corrosion-resistant materials are preferred for such applications to ensure compatibility with strict hygiene standards and durability in sanitary environments.
Yes, copper nickel 70/30 fasteners can be recycled after use. The alloy’s composition primarily consists of copper and nickel, both of which are highly recyclable materials. Recycling processes involve melting down the used fasteners to extract the copper and nickel for reuse in various applications, promoting sustainability and resource conservation.
To select the right copper nickel 70/30 fasteners, assess application requirements for corrosion resistance, mechanical strength, and compatibility. Choose fasteners meeting specifications like size and thread type, from reputable manufacturers. Consider factors like environment, load-bearing capacity, and budget to ensure optimal performance and longevity in your specific application.
