Alloy 400 (UNS N04400/ W.Nr. 2.4360 / 2.4361)

Alloy K-500 (UNS N05500/ W.Nr. 2.4375)

Standard & Grades

It has a specific gravity of 8.83, an electrical conductivity of approximately 34% IACS, and (in the annealed state) a hardness of 65 Rockwell B. MONEL® alloy 400 A nickel-copper alloy with high strength and excellent corrosion resistance in a range of media including sea water, hydrofluoric acid, sulfuric acid, and alkalis. Used for marine engineering, chemical and hydrocarbon processing equipment, valves, pumps, shafts, fittings, fasteners, and heat exchangers.

Alloy 401 A copper-nickel alloy designed for specialized electrical and electronic applications. It has a very low temperature coefficient of resistance and medium-range electrical resistivity. Used for wire-wound precision resistors and bi-metal contacts.

Alloy 404 Composition of this alloy is carefully adjusted to provide low Curie temperature, low permeability, and good brazing characteristics. Because its low permeability is not significantly affected by processing and fabrication, the alloy is particularly suitable for electronic parts. It can be fabricated by the same procedures used for MONEL alloy 400. The alloy can be joined to itself by the gas tungsten-arc welding process without the addition of filler metal.

Alloy R-405 The free-machining version of MONEL alloy 400. A controlled amount of sulfur is added to the alloy to provide sulfide inclusions that act as chip breakers during machining. Other characteristics are essentially the same as those of MONEL alloy 400. Used for meter and valve parts, fasteners, and screw-machine products.
