These Cupro nickel screws have good strength at moderately elevated temperatures and excellent cold and hot workability. Cupro-nickel 90/10 fasteners are therefore used for piping systems, marine hardware, and occasionally propellers, hulls of premium tugboats, crankshafts, fishing boats, and other related working boats. Commonly used fasteners to hold the machine parts together are copper-nickel 90/10 screws. Cupro Nickel 90/10 screws come in a variety of forms, including Cupro Nickel 90/10 set screws, socket head cap screws, and button head socket screws, among others.
These Copper Nickel 90/10 Nuts are also ideal for control resistors and thermocouples due to their medium resistivity and low-temperature coefficient of resistance. Our Copper 90/10 Bolts have exceptional resistance to erosion and impingement due to turbulent water containing air bubbles and silt flowing at high velocities due to the inclusion of controlled amounts of iron and manganese. These copper-nickel 90/10 screws also contain significant amounts of iron and manganese, which are required for good corrosion resistance. The Cupro-nickel 90 / 10 Bolts’ high oxidation resistance is visible in moist air and steam.
