Hakan Nickel Alloys, based in Istanbul, Turkey, specializes in crafting and supplying Copper Nickel Stud Bolts designed for tough environments like marine, offshore, and industrial settings. Renowned for their reliability, precise dimensions, and resistance to corrosion, these stud bolts adhere to international standards while also catering to specific customer needs. The company is committed to delivering consistent quality and durability, especially in harsh conditions involving saltwater, chemicals, or high pressure. Their Copper Nickel Stud Bolts are expertly designed to ensure secure fastening in piping systems, heat exchangers, and structural assemblies that face constant moisture or corrosive elements.
Typically made from 90/10 (90% copper, 10% nickel) or 70/30 (70% copper, 30% nickel) alloys, Copper Nickel Stud Bolts are chosen based on the specific service conditions they will encounter. These alloys are known for their outstanding corrosion resistance in seawater, brine, and mildly acidic environments. With tensile strength usually between 300–500 MPa, they offer the mechanical strength needed for low- to medium-pressure applications. Additionally, Copper Nickel is resistant to stress corrosion cracking, erosion, and hydrogen embrittlement. The material is thermally stable, non-magnetic, and resistant to biofouling, making these bolts ideal for critical installations that require durability, easy maintenance, and structural integrity.
