Fajar Metals, a leading manufacturer and supplier located in Jakarta, Indonesia, specializes in precision-engineered Copper Nickel Stud Bolts that are built to last and perform exceptionally well in corrosive and marine settings. Crafted from high-quality Cu-Ni 90/10 and 70/30 alloys, these stud bolts are perfect for applications in offshore platforms, shipbuilding, desalination, and chemical processing. Fajar Metals offers a variety of sizes, threads, and finishes that meet global standards like ASTM B151, B467, and ASME B16.5. Renowned for their impressive mechanical strength and resistance to corrosion, these bolts guarantee secure and durable fastening even in the toughest conditions.
Copper Nickel Stud Bolts are generally made from Cu-Ni 90/10 (90% Copper, 10% Nickel) or Cu-Ni 70/30 (70% Copper, 30% Nickel) alloys, with small amounts of Iron (Fe) and Manganese (Mn) added to boost strength and seawater corrosion resistance. These bolts showcase tensile strength between 275–420 MPa, yield strength from 105–180 MPa, and remarkable ductility and toughness. Cu-Ni stud bolts are particularly resistant to biofouling, chloride stress corrosion, and pitting, making them dependable in submerged and humid environments. Their excellent weldability and formability cater to a variety of installation requirements.
