What is Monel Alloy 401?
Monel Alloy 401 is also commonly referred to as UNS N04401. It is a nickel-copper alloy that was initially created for systems that needed high electronic and electrical properties coupled with the same corrosion resistance that is characteristic of all Monel alloys.
One of the greatest characteristics of this Alloy 401 is its ability to maintain its electrical properties at low temperatures as a low temperature coefficient makes it ideal for the manufacture of precise electrical and electronic hardware where changes due to temperature would affect performance.
Key Characteristics of Monel Alloy 401
- Excellent electrical conductivity
- Outstanding corrosion resistance
- Good mechanical strength
- Low temperature coefficient
- High resistance to seawater environments
- Excellent dimensional stability
- Good machinability
- Suitable for cryogenic and low-temperature applications
