Copper Nickel 90/10 Fasteners are used in many industries, but more so in marine salt water environments, as they offer superb resistance to corrosion from salt water. Cu-Ni 90/10 Marine fasteners properties is that it contains 90% copper and 10% nickel and to it are also added manganese and iron, to increase its resistance to corrosion. Copper Nickel 90/10 Bolts has a Tensile Strength (annealed) of 52000 psi (359 MPa) and it has a Tensile Strength (rolled-H04 for flat products/ hard drawn-H80 for tubing) of 78000 psi (538 MPa). The Poisson’s Ratio of Copper Nickel 90/10 Socket Set Screw (C71500 annealed) is 0.325. In steam and moist air, the high oxidation resistance of 90/10 Cu-Ni Washers is clearly visible. The addition of chromium, niobium, iron or manganese to Cu-Ni 90/10 Hex Head Bolt increases its resistance to corrosion and it also increases its strength.

ASTM B151 90/10 Cupro Nickel Screws has inherent resistance to biofouling and it also has excellent fabricability. Even at high temperature levels, Cu UNS C70600 Coupling Nut & Cu-Ni 90/10 Spring Washer have thermal stability. ASME SB 152 Cu-Ni Flat Washer has stress corrosion cracking resistance and high oxidation resistance. The Thermal Expansion Co-efficient of Copper nickel (@20-300°C/68-572°F) is 9.00 µin/in °F (16.2 µm/m °C). Cu-Ni WERKSTOFF NR. 2.0872 Full thread stud has a Rockwell B Hardness of 69. The Chemical Composition of 90/10 Copper Nickel Flange Bolts is Cu 71.25-76.5, Fe ≤ 0.20, Pb ≤0.050, Mn ≤ 1.0, Ni 23.5-26.5 and Zn ≤ 1.0. The Yield Strength (annealed) of ASME SB 152 90/10 Nut Bolt is 15000 psi (103 MPa). Bolts of 90/10 Copper Nickel are used in many applications like fittings, valves, flanges, pump bodies, paper machine construction, water boxes, tube mounting material, salt water piping and pipe fittings, pipelines in shipbuilding and solder fittings.
