Russ Fasteners produces and distributes high-performance Copper Nickel Nuts in Singapore, Pulau Ujong, providing essential corrosion-resistant fastening solutions for extreme applications. Made from CuNi 90/10 and 70/30 alloys, nuts are specifically made to be used with copper nickel studs and bolts for maximum compatibility and anti-corrosion. Russ Fasteners guarantees precision dimensions, high strength, and long-term durability in all their copper nickel fasteners. Suitable for marine, chemical processing, and desalination applications, Copper Nickel Nuts provide secure fastening with excellent resistance to saltwater corrosion and biofouling.
Copper Nickel Nuts are made of 90% copper and 10% nickel (CuNi 90/10) or 70% copper and 30% nickel (CuNi 70/30), which are usually alloyed with small traces of iron and manganese to enhance strength as well as corrosion resistance. Copper Nickel Nuts provide tensile strengths of 300–500 MPa, and better resistance to stress corrosion, erosion, and pitting. They are non-magnetic and non-sparking, working consistently in marine and chemical applications. Copper Nickel Nuts have high mechanical strength and threading when exposed to seawater, acid, and industrial chemicals for an extended period of time.

Copper Nickel Nuts find extensive application in seawater cooling systems, heat exchangers, ship building, and offshore drilling. Copper Nickel Nuts are vital to secure copper nickel bolts and studs in saltwater exposure or chemical process applications. They are perfect for flanged pipe connections, pumps, and valves in seawater desalination plants, coastal power stations, and water treatment plants. Their non-magnetic properties also qualify them for sensitive instrumentation in naval vessels and research vessels. Copper Nickel Nuts are an integral part of fastening systems demanding long-term corrosion resistance and mechanical reliability in highly corrosive, wet, or chemically active environments.
Copper Nickel nuts at Russ Fasteners are packed in order to retain the quality of the product and we take utmost care while packing. Every nut is covered separately to avoid getting damaged, corroded or contaminated in the course of transportation.
