Copper Nickel 70/30 stud bolts are made of 70% copper and 30% nickel, with a lightweight combination of steel and manganese to increase strength and corrosion resistance These bolts exhibit excellent mechanical properties, such as 380 MPa tensile strength and 120 MPa yield strength. They provide greater resistance to seawater erosion, pressure corrosion cracking, and bio odorization, making them ideal for marine and coastal applications. The alloy’s excellent thermal stability and weldability further enhance its versatility. Copper nickel 70/30 stud bolts ensure long-term performance and reliability in harsh environments, reduce maintenance costs and extend service life.
