These CuNi Fasteners can also be adjusted in terms of thickness and size to meet the needs of our clients, Copper-nickel fasteners are alloys that contain iron, manganese, copper, and nickel content, Cupronickel is not damaged when exposed to seawater, and may also be used in a range of sectors, such as oil & gas, petrochemical, and paper manufacturing, these Cu Ni 70/30, 90/10 Fasteners can also be modified in terms of thickness and size to meet the needs of our clients.

Whenever copper-nickel fasteners are exposed to sea water, they form an oxide layer that protects them from damage. Other features of copper-nickel fasteners include corrosion resistance, ductility, and strength. Copper-nickel fasteners do not suffer from undesirable macrofouling. Copper-nickel is also a good thermal conductor. Copper-nickel has good formability, making it highly effective in many industries.

In addition to marine engineering and armaments manufacturing, coin manufacturing, chemical plants, desalination plants, petrochemical plants, and power generation, four main types of Cu-Ni fasteners are available. These include bolts, washers, screws, and nuts. Cu-Ni fasteners do not show any kind of ferromagnetism, which makes them useful in many industries. Testing is considered a crucial here to maintain the quality of this fastener.
