Equivalent designations: Monel 401, UNS N04401 Monel 401 Trade Name:Alloy401; UNS N04401 Monel 401 is a nickel-copper alloy with a very low coefficient of electrical resistivity and resistance to a wide variety of corrosive conditions. Like with commercially pure Nickel, Alloy 401 is low in strength in the annealed condition and can only be cold worked to a maximum of 120 KSI. Monel 401 has a very low temperature coefficient of resistance and medium-range electrical resistivity. It is used in specialized electrical and electronic Applications.
