Overview
As a leading supplier & manufacturer in China, AEETHER supply cost-effective Monel 404 Products.
MONEL® nickel-copper alloy 404 (UNS N04404) is used primarily in specialized electrical and electronic applications.
The composition of MONEL alloy 404 is carefully adjusted to provide a very low Curie temperature, low permeability, and good brazing characteristics.
Mechanical Properties
Alloy 404’s permeability (measured at 27°F with a field strength of 0.5 oersted) will not exceed 1.1. Because its low permeability is not significantly affected by processing and fabrication, the alloy is particularly suitable for electronic parts.
Also, much of the strength of alloy 404 is retained at out-gassing temperatures. Its thermal expansion characteristics are sufficiently close to those of many other alloys to permit the firing of composite metal tubes with negligible distortion.
