Here at Brian Fasteners in Houston, USA, we are pleased to provide a strong range of fasteners for specialized use, among them our top–grade Copper Nickel Stud Bolts. For heavy-duty applications where sound, corrosion-resistant connections are a priority, these stud bolts are built to handle harsh conditions while delivering higher reliability and longer service life in mission-critical infrastructure and industrial applications.
Copper Nickel Stud BoltsCopper Nickel Stud Bolts are generally produced from alloys including 70/30 (C71500) or 90/10 (C70600). The 70/30 alloy consists of about 70% copper and 30% nickel and 90/10 includes 90% copper and 10% nickel with small amounts of iron and manganese. These compositions offer excellent corrosion resistance, particularly in seawater. Mechanical properties are characterized by high tensile strength (for example, 372-517 MPa for 70/30) and good ductility, which provides consistent performance under stress and temperature changes.

Copper Nickel Stud Bolts find wide applications in the marine and offshore sectors for joining heavy pieces in ship construction, underwater equipment, and offshore platforms because of their superior resistance to seawater corrosion and biofouling. They are also used in chemical and petrochemical facilities for pressure vessels, heat exchangers, and piping systems, in power generation plants where their thermal stability and resistance to corrosion are necessary for efficient operation.
