Elvis Nickel Alloys, a top-notch manufacturer and supplier located in Houston, USA, specializes in high-quality Copper Nickel Screws that are built to last in tough, corrosive, and marine settings. Made from robust Copper Nickel 90/10 (C70600) or 70/30 (C71500) alloys, these screws boast remarkable resistance to saltwater corrosion, biofouling, and stress corrosion cracking. With their outstanding thermal conductivity and non-magnetic features, Copper Nickel screws come in a variety of sizes, head types, and threading options, all while adhering to international standards like ASTM B151 and DIN/ISO for reliable and corrosion-resistant fastening solutions.
Typically, Copper Nickel Screws consist of 90% or 70% copper, 10% or 30% nickel, along with trace amounts of iron and manganese to boost strength and corrosion resistance. They provide moderate tensile strength (240–350 MPa) and excellent ductility, making them perfect for both threaded and formed components. These screws hold up well in high-temperature, high-salinity, and chemically aggressive environments. Thanks to their low biofouling properties and superior thermal stability, Copper Nickel screws are a trustworthy fastening choice in applications where performance and durability are essential.
