In seawater, Copper Nickel 70 / 30 Nuts have excellent corrosion rates which remain low as long as the maximum design flow velocity is not exceeded. This velocity depends on geometry and pipe diameter. Copper Nickel 90 / 10 Nuts have high resistance to crevice corrosion, stress corrosion cracking and hydrogen embrittlement that can be troublesome to other alloy systems.
Cupro nickel Hex Nuts naturally form a thin protective surface layer over the first several weeks of exposure to seawater and this provides its ongoing resistance. As a supplier, stockiest, exporter and manufacturer of Cupro nickel Heavy Hex Nuts, we provide these Fasteners in custom-built thicknesses and sizes according to exact requirements of our well-regarded patrons. We offer Cupro nickel Lock Nuts at economical prices to our consumers. Cupro nickel Self Locking Nuts are available in different dimentions, size, grades & thickness as per the clients requirments.
Cupro nickel Nylon Insert Nuts are alloys of copper (base metal with the largest individual content) and nickel with or without other elements, whereby the zinc content may not be more than 1%. When other elements are present, nickel has the largest individual content after copper, compared with each other element. Cupro nickel Coupler Nuts have special quality finishing and duress for long life, high pressure and zero defects
