Monel 401
Description
Monel 401 is a nickel-copper alloy with excellent electrical properties, especially a stable resistance at low temperatures. Unlike Monel 400, it’s valued for its reliable conductivity, making it ideal for precision electrical components like switches, sensors, and thermostats.
Application：
- Precision resistors
- Bi-metal contacts
- Electrical and electronic components
- Connectors
- Sensors
- Certain types of wiring
