Nickel 400

Nickel 400

Nickel 400 is a single-phase, solid-solution, nickel-copper alloy with excellent corrosion resistance to a wide range of media. Its unique composition blends the noble metal properties of copper with the passivating property of nickel.”

You can use Alloy 400 in many fields, especially marine and chemical processing. Typical applications are valves and pumps; pump and propeller shafts; marine fixtures and fasteners; electrical and electronic components; springs; chemical processing equipment; gasoline and fresh water tanks and much more.


Chemical Composition – The chemical composition is majorly nickel as would be expected. With a range of 63-70% nickel, it possesses high strength and corrosion resistance. The other major element is be copper which helps with heat dispersal as well as strength. This has a percentages ranging between 28 and 34%.

Corrosion Resistance – Nickel 400 is virtually immune to chloride ion stress corrosion cracking in typical environments.Its corrosion resistance is very good in reducing environments, but poor in oxidizing conditions. It is not useful if you want to oxidise acids, such as nitric acid and nitrous. Nevertheless, it withstands most alkalis, salts, waters, food products, organic substances and atmospheric conditions at normal and elevated temperatures.

NItronic 40Machinability – Nickel 400 showcases superb weldability and frequently appears in marine applications such as seawater valves and pump shafts. Chemical plant equipment, boiler feeders, and heat exchangers also utilize these tubes. Its high melting point and toughness under harsh conditions make it ideal for applications requiring high tolerance tubing.”
