Monel 404 (UNS N04404)
Monel 404 (UNS N04404) is a nickel-copper alloy which is used primarily in electrical and electronic application. Similar to Monel 401, the chemical composition of Monel 404 is carefully adjusted to provide a very low curie temperature, low permeability, and good brazing characteristics.
