Nickel alloys

ALLOY 400

UNS N04400

Alloy 400 is a nickel-copper alloy known for its excellent corrosion resistance, particularly in marine, chemical, and alkaline environments. It also offers good mechanical properties over a wide temperature range, as well as very good weldability and formability. Thanks to its metallurgical stability and resistance to harsh environments, it is widely used in the offshore, chemical, and energy sectors.
