Cupro Nickel C71500 Fastener Fittings

Cu-Ni 70/30 Fasteners are designed to deliver exceptional strength and corrosion resistance in marine, offshore, and industrial applications. These include hex head bolts, socket cap screws, studs, and nuts, manufactured according to ASTM B151, B152, and DIN 2.0882 standards. Resistant to seawater, bio-fouling, and chloride-induced pitting, they ensure long-lasting performance even in harsh climates. Custom sizes and designs are available to meet specific project needs. These fasteners are ideal for pipelines, desalination plants, and shipbuilding industries, providing reliable connections, high mechanical integrity, and smooth assembly in demanding environments.

Cu-Ni 70/30 specialty fasteners, such as Allen cap screws, pan head screws, wing screws, and spring washers, are widely used in marine and industrial systems. Their copper-nickel alloy construction resists corrosion, wear, and stress corrosion cracking. Suitable for high-pressure and high-velocity pipelines, these fasteners ensure secure connections and structural integrity. They comply with ASTM B151, B152, and ASME SB151 standards, offering reliable performance across seawater, desalination, and offshore applications. Available in customizable dimensions, these fittings provide easy installation and long-term durability, making them essential components for piping systems requiring high strength and corrosion resistance.

One of the key advantages of Incoloy 825 fasteners is their outstanding resistance to different forms of corrosion. They perform exceptionally well against sulfuric acid, phosphoric acid, nitric acid, and seawater. These fasteners exhibit superior resistance to pitting, crevice corrosion, and stress-corrosion cracking. In addition, they maintain strength and stability at both cryogenic and elevated temperatures, making them suitable for a wide range of environments. Sunrise Industries ensures precise manufacturing, resulting in fasteners with excellent tensile strength, yield strength, and elongation properties. Their ability to withstand both oxidizing and reducing environments makes them a reliable choice for industries dealing with corrosive media and high-pressure conditions.

Cu-Ni 70/30 hex head bolts provide exceptional corrosion resistance and high tensile strength, making them ideal for marine and industrial applications. Designed to withstand harsh seawater conditions and resist bio-fouling, these bolts maintain structural integrity even under high pressure and temperature. Manufactured as per ASTM B151 and DIN 2.0882 standards, they ensure precise fit and easy installation. Available in custom sizes, these bolts are suitable for pipelines, shipbuilding, and offshore installations, offering durability, reliability, and long-lasting performance in demanding environments.
