Hamad Fasteners, based in Riyadh, Saudi Arabia, stands out as a top manufacturer and supplier of premium industrial fasteners designed specifically for marine and corrosive environments. Our Copper Nickel Stud Bolts are expertly crafted to deliver outstanding performance in seawater, brine, and salt-laden conditions. These fasteners find their place in shipbuilding, offshore platforms, desalination plants, and heat exchanger systems. Built to meet international standards, our Copper Nickel stud bolts strike the perfect balance between corrosion resistance, durability, and mechanical reliability, even in the toughest applications.
Typically, Copper Nickel Stud Bolts are made up of either 90% copper and 10% nickel (90/10) or 70% copper and 30% nickel (70/30), with a touch of iron and manganese added to enhance strength and corrosion resistance. They offer moderate tensile strength (usually between 275–520 MPa), exceptional resistance to biofouling, and impressive performance in high-salinity and brackish water settings. This alloy maintains stability in varying temperatures and stands up to erosion, stress corrosion, and hydrogen embrittlement, making it a great choice for long-term use in submerged or wet environments.
