Russ Fasteners is a reliable Singapore, Pulau Ujong supplier of Copper Nickel Stud Bolts that deliver high-quality corrosion-resistant solutions for marine and chemical industries. Made with CuNi 90/10 or 70/30 alloys, these stud bolts exhibit exceptional strength and long-term performance in seawater-exposed conditions. Russ Fasteners assures all Copper Nickel Stud Bolts are precision-designed and quality-inspected to meet performance specifications. Suitable for flange joints and wet high-moisture assemblies, these stud bolts provide superior mechanical strength and resistance to pitting and crevice corrosion and are a critical component in offshore, shipbuilding, and desalination plant applications.
Copper Nickel Stud Bolts are generally of 90/10 or 70/30 copper-nickel alloys. The alloys include copper, nickel, and small amounts of iron and manganese that improve strength and corrosion resistance. Having tensile strengths ranging from 300–500 MPa, they possess superior mechanical properties in harsh marine environments. They have good resistance to hydrogen embrittlement, biofouling, and thermal cycling, and provide very good localized corrosion resistance. Copper Nickel Stud Bolts are non-sparking, heat-resistant, and compatible with high-salinity and chemically reactive conditions. Their consistent strength suits them well for high-pressure-bearing assemblies and flanged joints.

Copper Nickel Stud Bolts are applied in marine ships, seawater desalination plants, heat exchangers, seawater piping systems, and oil platforms in the sea. Their resistance to corrosion makes them perfectly suited for fastening pipe flanges, valves, pumps, and heat exchanger covers when they are exposed to saltwater. They are also utilized in coastal power plant water treatment systems and condenser assemblies. Copper Nickel Stud Bolts prevent galvanic corrosion in assemblies with comparable metals and provide a secure, reliable connection in harsh marine or chemical conditions. Copper Nickel Stud Bolts are popular for use where mechanical strength and long-term corrosion resistance are needed in wet or underwater environments.
