Fasteners are small components that play a crucial role in the manufacturing industry. They hold together two or more materials, ensuring the final product is structurally sound. Manufacturers use various types of fasteners, depending on the application and the type of material used. Cu-Ni, or Copper-Nickel alloys, are known for their excellent corrosion resistance, electrical conductivity, and thermal conductivity. These properties make Cu-Ni alloy fasteners particularly useful in harsh environments, where other material fasteners would quickly erode.

Cu-Ni 70 Fasteners come in various shapes and sizes. Commonly used Cu-Ni 70 fasteners include nuts, bolts, screws, washers, and studs. These fasteners are made from a Cu-Ni alloy that contains 70 per cent copper and 30 per cent nickel. Cu-Ni 70 fasteners are uniquely suited for marine applications because they resist saltwater corrosion. They also have excellent resistance to biofouling, a buildup of marine life on surfaces submerged in seawater. Cu-Ni 70 fasteners are compatible with stainless steel but not aluminium or zinc.

Cu-Ni 30 fasteners are made from a Cu-Ni alloy that contains 30 per cent copper and 70 per cent nickel. These fasteners are known for their excellent resistance to temperatures and mechanical stress, making them well-suited for high-temperature applications. Cu-Ni 30 fasteners are commonly used in the aerospace industry, where they are used for cladding and equipment in supersonic aircraft. They are also used in electric power plants and nuclear reactors. Cu-Ni 30 fasteners are compatible with various materials, making them ideal for use in multiple industries.

The unique properties of Cu-Ni 70 and 30 fasteners come with many benefits. These fasteners have excellent corrosion resistance, even in harsh environments, which means they last longer than other fasteners. They are also highly durable, ideal for applications with paramount strength and stability.
