Monel 401 (UNS N04401) is a nickel-copper alloy designed with excellent resistance to seawater, steam, and chemical environments, while also offering unique electrical and thermal conductivity properties. With a balanced combination of strength, ductility, and corrosion resistance, Monel 401 is especially suitable for electrical and electronic applications where both durability and conductivity are required.
This alloy is widely used in the manufacture of electrical resistance wires, thermostats, heating elements, marine components, and industrial equipment. Its ability to maintain stability under corrosive and high-temperature conditions makes Monel 401 a reliable choice for critical applications. It is typically available in the form of wires, rods, bars, and strips, serving industries such as marine engineering, power generation, and electronics.
