We offer These Copper Nickel 70/30 Bolts as per DIN, ISO, JIS or ANSI Standard.
Corrosion Resistance: The main advantage is its excellent corrosion resistance, especially in marine environments. Copper Nickel 70/30 bolts are resistant to seawater corrosion, making them ideal for shipbuilding, marine structures, and other marine applications.
Easy to manufacture: Copper Nickel 70/30 is relatively easy to manufacture using conventional methods such as machining, welding and fabrication. This simple construction contributes to versatility and is suitable for various applications.
Thermal Stability: Copper Nickel 70/30 bolts exhibit excellent thermal stability, which means that they can maintain their mechanical properties at high temperatures. This characteristic makes them suitable for use in hot energy environments or significant corrosion resistance loss.
Antibacterial properties: Copper and its alloys, including copper-nickel and 70/30, have natural antibacterial properties. This property is particularly useful in applications where microbial growth is required to be inhibited, such as in the food and beverage industry or medical devices
High strength: Despite its corrosion resistance, copper-nickel retains good mechanical properties with a high strength of 70/30. This makes it suitable for applications where strength and corrosion resistance are important, such as marine and coastal structures under large loads.
Copper Nickel 70/30 Bolts applications are as diverse as the industries they serve driven primarily by the aerospace, railway, construction and automotive industries with petrochemical, nuclear, medical, Oil & Gas, Chemical, Pharmaceutical, Food & Beverage, Nuclear, Thermal Power plants, Paper and Pulp, marine and mining, etc.
Shipbuilding: Copper-nickel 70/30 bolts are widely used for various applications, such as hulls, piping systems, and offshore platforms. Their corrosion resistance makes them ideal for enduring harsh marine environments.
Marine Equipment: Bolts made of 70/30 lead nickel are suitable for oil rigs, platforms, submarines and other offshore structures where salt water and corrosion are important
Desalination: In seawater desalination plants, copper-nickel 70/30 bolts are used in equipment and piping systems because of their corrosion resistance
Power generation: These bolts are used in power plants, especially those near coastal areas, where they are confined to salt air or seawater
Chemical Industry: In chemical plants where corrosive materials are used, copper-nickel 70/30 bolts are used for valve, pump and piping systems
Understand the application: Determine the specific application for which you need your bolts. Copper nickel 70/30 bolts are commonly used in marine environments due to their excellent resistance to seawater corrosion. However, they are also suitable for other important properties such as corrosion resistance and strength.
Check environmental conditions: Consider the environment associated with the bolts. Copper nickel 70/30 bolts are particularly suitable for marine and offshore applications in salt water but are also used in chemical processing, oil and gas, and electrical industries.
Quality and Standards: Ensure bolts meet quality standards and relevant specifications. Refer to ASTM B151 and other certifications for copper-nickel 70/30 products.
Size and Specifications: Specify your application’s size, thread pitch, and other important specifications. Bolts come in various sizes and configurations, so make sure they fit your needs perfectly.
Check Material Suitability: Make sure the copper-nickel is 70/30 compatible with the material to be included. This is especially important for preventing galvanic corrosion in areas of heterogeneous metals.
