The company‘s emphasis on precision, quality control, and customer support makes it an approved supplier of Copper Nickel Bolts for applications requiring high criticality in severely corrosive and high-moisture industry segments.
Copper Nickel Bolts are usually made up of 90% copper and 10% nickel (CuNi 90/10) or 70% copper and 30% nickel (CuNi 70/30) and occasionally alloyed with a small percentage of iron and manganese to enhance strength. These bolts have excellent resistance to seawater corrosion, stress corrosion cracking, and biofouling. The tensile strength varies from 300 to 500 MPa based on alloy grade and condition. Copper Nickel fasteners also have good heat conductivity and high resistance to hydrogen embrittlement, thus being suitable for marine and chemical processing applications.
