Copper Nickel 90/10 Fasteners supplied by Adinox Overseas are well known in many industries as far as combined top performance, high strength and, of course, excellent corrosion resistance is concerned, where marine and offshore industries are concerned. These fasteners are made of an alloy with UNS C70600 brass alloy consisting of 90 percent copper and 10 percent nickel with minor traces of iron and manganese to make it stronger and corrosive resistant.
Copper nickel 90/10 fasteners adhere to ASTM B151 standard and are commonly known under the generic universal name of copper nickel 90/10.CuNi 90/10 Fasteners are very well used in instances like shipbuilding, generation of power, heat exchanges and desalination plantations. They possess high thermal conductivity and mechanical versatility; this is why Copper Nickel 90/10 is widely used in Copper Nickel 90/10, Adinox Overseas being one of its main producers and exporters produces and exports a complete line of fasteners in the form of bolts, nuts, washers, threaded rods, screws, studs, and special items as well.
The UNS C70600 Fasteners have excellent mechanical strength and good resistance to corrosion in brackish and salt water and are therefore preferred in piping systems underwater as well as condenser tubes. They can be utilized in complicated marine structures, under demanding operational conditions, they are simple to produce and also have very good weldability. The alloy composition has iron whose presence improves the resistance to impingement attack particularly experienced in high seawater speed systems.
