Copper-Nickel Fasteners
Copper Nickel 90/10 and 70/30 fasteners, Cu-Ni 90/10 and 70/30 fasteners Manufacturer, Exporter & Suppliers in India.
ASTM B151 UNS C71500 70/30 and ASME SB151 UNS C70600 90/10 fasteners Suppliers.
Widely used in industries like chemical processing, food processing, petrochemicals, and power generation, these fasteners exhibit excellent resistance to alkaline solutions and neutrals. While effective conductors of heat, they display lower electrical conductivity than other fasteners. Special care is needed to prevent galvanic corrosion when in contact with other metals in acidic environments. Known for toughness, strength, and remarkable resistance at elevated temperatures, these fasteners undergo thorough testing, including positive material tests, pitting resistance tests, hardness tests, chemical tests, and micro/macro tests. For safe transportation, we offer various packaging options like wooden boxes, bundles, and plastic boxes.
Copper Nickel 90-10 Fasteners, composed of 90% copper and 10% nickel, along with elements like manganese and iron, are well-suited for architectural and marine applications. They exhibit good toughness and ductility at elevated temperatures, superior resistance to corrosion, stress corrosion, erosion, and hydrogen embrittlement. These fasteners also display excellent mechanical properties at cryogenic temperatures, ensuring high inherent resistance to fouling and remarkable formability. With good thermal stability and moderate strength at high temperatures, these fasteners are a reliable choice for various applications.
Copper Nickel Fasteners Specifications
Copper nickel fasteners, in 90-10 and 70-30 alloys, are crafted for top-notch performance. The 90-10 type excels in marine settings, tackling seawater corrosion, while the 70-30 variant finds the perfect balance for strength and corrosion resistance. Ideal for maritime and offshore use, these fasteners guarantee durability and longevity, thanks to their high-quality materials and precise manufacturing.

Copper Nickel Fasteners Chemical Composition
Crafted from 90-10 cupro nickel (90% copper, 10% nickel) and 70-30 cupro nickel (70% copper, 30% nickel), these fasteners ensure durability and fight corrosion. The 90-10 type excels in seawater, tackling corrosion and biofouling, while the 70-30 type offers strength and thermal stability, perfect for tough marine and industrial settings. With a strong defense against corrosion, these fasteners guarantee reliability and long life, crucial in maritime, offshore, and chemical processing systems.
