Corrosion Resistance of Cupro Nickel 90/10 Fasteners

Cupro Nickel 90/10 Fasteners have a high corrosion resistance due to the alloy's presence of nickel. Adding nickel to copper improves its resistance to acids and other corrosive agents. Cupro Nickel 90/10 fasteners can withstand the corrosive effects of seawater, brine, and salt spray. They also resist crevice corrosion in tight spaces where oxygen is depleted.

Chemical Composition of Cupro Nickel 90/10 Fasteners

Cupro Nickel 90/10 is an alloy of 90% copper and 10% nickel. It also contains small amounts of iron, manganese, and zinc. Adding nickel to copper improves the alloy's strength, flexibility, and corrosion resistance. The iron in the alloy improves its resistance to erosion, while the manganese improves its resistance to seawater corrosion.

Applications of Cupro Nickel 90/10 Fasteners

Cupro Nickel 90/10 fasteners are widely used in the marine, oil, gas, and chemical industries. They are used in seawater systems, desalination plants, heat exchangers, and oil rigs. Cupro Nickel 90/10 fasteners are also used in the construction of ships and submarines and in the manufacturing of valves, pumps, and turbines.

Heat Treatment of Cupro Nickel 90/10 Fasteners

Cupro Nickel 90/10 is a non-heat treatable alloy. The welding of Cupro Nickel 90/10 fasteners should be carried out at low-wattage settings to avoid cracking. The alloy can be cold-worked to improve its strength and flexibility. However, excessive cold working can lead to stress cracking in the material.
