Corrosion-resistant nickel-copper alloy B127

Equal material : ASME SB-127, AMS 4554, JIS NW4400 , UNS N04400, NiCu30Fe W-Nr: 2.4360, MCu-28-1.5-1.8 , BS NA 12

B127 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.
