Corrosion-resistant nickel-copper alloy UNS N04400

Equal material : B127, ASME SB-127, AMS 4554, JIS NW4400 , UNS N04400, NiCu30Fe MCu-28-1.5-1.8,BS NA 12

UNS N04400 alloy is a kind of corrosion resistance of nickel copper alloy, its organization into a single phase high strength of solid solution. Having excellent corrosion resistance in hydrofluoric acid and fluorine gas medium; also have excellent corrosion resistance to hot concentrated alkaline solution; at the same time also resistant to neutral solution, halogen, high temperature, water, sea water, all kinds of food, a variety of organic compounds in atmospheric corrosion. Generally no stress corrosion crack, good cutting performance.
