Copper Nickel 90/10 bolts are a go-to choice in the marine, offshore, and chemical processing sectors, thanks to their outstanding resistance to saltwater corrosion and biofouling. In shipbuilding, you’ll find them in seawater cooling systems, condenser bolts, and hull fittings. Offshore oil and gas platforms depend on these bolts for risers, flanges, and structural joints that face seawater exposure. In desalination and water treatment facilities, they’re utilized in brine systems and evaporators. The chemical industry also counts on these bolts for mildly acidic process systems. Their long-lasting performance, low maintenance needs, and corrosion resistance make them indispensable for high-reliability applications.
Copper Nickel 90/10 bolts that we sell at Bilal Fasteners are carefully packed so that they can reach the client in the best condition.
