Ninthore Overseas is one of the Leading Manufacturer And Exporter of Cupro Nickel 90 Washers, Copper Nickel 90 / 10 Flat Washers has tensile, hardness, impact, creep and fatigue features, which have been abstracted from the relevant original literature. Cu-Ni 90 / 10 Lock Washers are most commonly specified within the marine, offshore, chemical, petrochemical and shipbuilding industries. Cupro Nickel 90 / 10 Sealing Washers are also widely used for handling seawater in all types of heat exchanger and cooling plant. Nickel in Copper Nickel 90 / 10 Split Washers is soluble in copper and this renders the copper nickel alloys as single phase alpha structures. 

Cu-Ni 90 / 10 Slot Washers is a typical mix is 75 % copper, 25 % nickel, and a trace amount of manganese, where in the past, true silver coins were debased with such cupronickel. Cupro Nickel 90 / 10 Machine Washers are attacked by chromic, hydrochloric and nitric acids. Copper Nickel 90 / 10 Star Washers is also resistant to the alkali chlorides, nitrates, sulfates and to ammonia and ammonium compounds.
