What are Cupronickel Nuts?

Cupro Nickel Nuts These are fasteners that are made of an alloy between copper and nickel, which have been proven to be very resistant to corrosion and have great strength. The metal combination enables these nuts to work efficiently in adverse environments and more so where consistent exposure to seawater, moisture or high temperatures is experienced. They do not wear out easily or become brittle, and therefore they are used in the harsh conditions of service.

The applications of Cu-Ni heavy nuts are found in marine, automotive, oil and gas, power generation and industrial manufacturing. They are usually fitted on pumps, engines, heat exchangers, desalination plants and structural assemblies. Cupro-nickel fasteners are also more acceptable in electrical systems where there is a need to use components which do not corrode easily. They come in various forms, such as cupro nickel bolts, washers, screws and studs, and are extensively used in any industry.
