MONEL alloys contain nickel and copper as the main components. Robert Crooks Stanley discovered this alloy in 1901 while working at the International Nickel Company.
There are a number of MONEL alloys available commercially including MONEL 400, 401, 404, R-405, 450 and K-500. The standard forms in which MONEL alloys are available are hexagon, flats, forging stock, tube and pipe.
MONEL 404 has a relatively high copper content, hence is suitable for electric and electronic applications. The content of the elements that make up the MONEL 404 is adjusted such that the alloy has a very low Curie temperature, low permeability and good brazing characteristics.
This datasheet will look into the chemical composition, properties and applications of MONEL 404 alloy.
The chemical composition of MONEL 404 alloy is given in the following table.
| Element | Content (%) |
|---|---|
| Nickel, Ni | 50 - 57 max |
