Description

[Inco] A registered trademark for a series of metal alloys composed of Nickel and Copper. Monel was introduced in 1905 by the International Nickel Company. First prepared as a natural alloy, Monel was composed of about 67-70% nickel, 25-29% copper with small amounts of Iron, Manganese, and/or Silicon. From 1909 to the mid-1950's, this bright white metal was popular for architectural applications (sinks, countertops, grillwork, roofing, etc.) because it was stronger than steel, readily fabricated, and corrosion resistant. Currently, Monel alloys are synthetically mixed and are used may applications including marine parts and nontarnishing staples.

-S Monel has 3.75% silicon and is used for castings and valves.

-K Monel is an age hardened version of the natural alloy.

-R Monel contains 67% nickel, 30% copper and 0.35% sulfur. It has high strength.

-H Monel contains 63% nickel, 31% copper, 3% silicon, 2% iron, 0.7% manganese.

-Z Monel contains 98% nickel.

Synonyms and Related Terms

Monel-Plymetyl; monel (Fr.); Monelmetall (Deut.)

Other Properties

Monel alloys can be finished as a white silver with a high polish, as a pewter-like matte gray or with a thin black oxide layer. Indoors, it oxidizes to form a clear layer, but can form a gray-green film outdoors.
