MONEL® alloy R-405
The free-machining version of MONEL alloy400. A controlled amount of sulfur is added tothe alloy to provide sulfide inclusions that actas chip breakers during machining. Othercharacteristics are essentially the same as thoseof MONEL alloy 400. Used for meter and valveparts, fasteners, and screw-machine products.
Composition of this alloy is carefully adjusted toprovide low Curie temperature, low permeability,and good brazing characteristics. Because its lowpermeability is not significantly affected byprocessing and fabrication, the alloy is particu-larly suitable for electronic parts. It can befabricated by the same procedures used forMONEL alloy 400. It can be joined to itself bythe gas tungsten-arc welding process withoutthe addition of filler metal.
