Copper Nickel 70/30 Fasteners

Copper Nickel 70/30 Fasteners

In seawater, Cu-Ni 70 / 30 Fasteners have excellent corrosion rates, which remain low as long as the maximum design flow velocity is not exceeded. Cupro Nickel 70 / 30 Fasteners have high resistance to crevice corrosion, SCC and hydrogen embrittlement that can be troublesome to other alloy systems. Copper Nickel 70 / 30 Nuts naturally form a thin protective surface layer over the first several weeks of seawater exposure, which provides its ongoing resistance. Additionally, Copper Nickel 70 / 30 Bolts have a high inherent bio-fouling resistance to attachment by macrofoulers living in the seawater.

To use this property to its full potential, Copper Nickel 70 / 30 Washers must be free of the effects of or insulated from any form of cathodic protection. Copper Nickel 70 / 30 Screws can show high corrosion rates in polluted or stagnant seawater when sulfides or ammonia are present. It is essential to avoid exposure to such conditions in Copper Nickel 70 / 30 Stud Bolts, particularly during commissioning and refit while the surface films are maturing. Ferrous sulfate dosing to seawater systems in Cu-Ni 70 / 30 Nuts can provide improved resistance. As copper and nickel alloys are with each other easily and have simple structures, Cu-Ni 70 / 30 Bolts are ductile and willingly fabricated.
