We are pretty much engaged in giving a wide spread variety of Copper Nickel Washers. In seawater, Cupr nickel Flat Washers 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. Cupro nickel Punched Washers have high resistance to crevice corrosion, stress corrosion cracking and hydrogen embrittlement that can be troublesome to other alloy systems.
Cupro nickel Machined Washers 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 Square Washers, we provide these Fasteners in custom-built thicknesses and sizes according to exact requirements of our well-regarded patrons. We offer Cupro nickel Spring Washers at economical prices to our consumers. Cupro nickel Lock Washers are available in different dimentions, size, grades & thickness as per the clients requirments.
