Fajar Metals, a top-notch manufacturer and supplier located in Jakarta, Indonesia, specializes in high-quality Copper Nickel 90/10 Stud Bolts designed for tough marine and industrial settings. These bolts are crafted in line with international standards such as ASTM B151, B152, and DIN/ISO, making them renowned for their outstanding corrosion resistance, mechanical strength, and reliability in humid and salty environments. Fajar Metals offers a diverse selection of threaded stud bolts complete with nuts and washers, ensuring secure fastening in piping systems, heat exchangers, desalination units, and shipbuilding projects. The Cu-Ni 90/10 alloy guarantees remarkable durability, resistance to biofouling, and straightforward installation.
Copper Nickel 90/10 Stud Bolts consist of about 90% Copper and 10% Nickel, with minor additions of Iron (up to 1.5%) and Manganese to boost strength and corrosion resistance. These bolts typically showcase a tensile strength ranging from 275 to 370 MPa, a yield strength of 105 to 150 MPa, and impressive elongation and thermal conductivity. The 90/10 alloy offers robust protection against seawater corrosion, erosion, biofouling, and stress cracking, even with extended exposure. Their metallurgical stability and non-magnetic characteristics make them perfect for critical marine and industrial applications that demand secure, high-strength fastening.
