Monel 401 Description:

Monel 401, known as UNS N04401, is a nickel-copper alloy used in electronic and electrical applications. The alloy has low temperature resistivity and medium potential resistivity.
Not only that, this alloy also has the ability to weld using GTAW (tungsten arc welding) or resistance welding. Monel 401 is available in wire forms primarily for bimetallic contacts or precision resistors (wire-wound).
Similar to the commercial pure metal nickel, Monel 401 has low strength under annealing conditions and can only be processed up to 120 KSI.

Main features:

Tempering: Monel 401 alloy has cold rolling characteristics that adapt to different tempering.

Corrosion resistance: The corrosion resistance of Monel 401 is similar to that of Monel 400.

Heat treatment: This special alloy cannot be hardened by heat treatment.

Weldability: The Monel 401 has amazing weldability at low temperatures.

Possible alternative grades:

Monel Alloy 400: Popular for its high strength and corrosion resistance in alkaline or acidic environments.

Monel 404: Low permeability, reduced Curie temperature and excellent brazing properties make Monel 404 the ideal choice.

Monel R-405: It is a free-working grade of alloy 400 with a controlled sulfur content in its structure.

Monel 450: Monel 450 has excellent fatigue strength and high thermal conductivity.

Monel K-500: The Monel K-500 is designed with outstanding advantages such as hardness and strength.
