Strings on Electric Guitar; MFA 2001.239

Description

[Special Metals Corporation, formerly Inco] A registered trademark for a series of metal alloys composed of Nickel and Copper. In 1901, Monel was created by Robert Crooks Stanley in 1901, who worked for the International Nickel Company. It was patented in 1906. As a natural alloy, the first 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-1950s, variations of this bright white metal were 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 used as marine parts and nontarnishing staples. Monel is used as the material for valve pistons or rotors in some higher quality musical instruments such as trumpets, tubas, French horns as well as for mandolin and electric bass strings (Gibson Guitar 1930 and RotoSound 1962). Additionally Monel was used for the strings on guitars by Gibson Guitars.

Early desginations were specified as:

-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.

More recent designations are numbered as:

Trade Name ASTM/AISI

Alloy type

UNS  %Cu  %Al  %Ti  %Fe  %Mn  %Si  %Ni
Monel 400 B 127, B 164 N04400 28–34 2.5 max 2.0 max 0.5 max 63 min
Monel 401 N04401 28–34 2.5 max 2.0 max 63 min
Monel 404 N04404 Rem 0.05 max 0.5 max 0.1 max 0.1 max 52–57
Monel K-500 B 865 N05500 27–33 2.3–3.15 0.35–0.85 2.0 max 1.5 max 0.5 max 63 min
Monel 405 B 164 N04405 28–34 2.5 max 2.0 max 0.5 max 63 min

Synonyms and Related Terms

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

Physical and Chemical 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.

Nickel metal and alloys are skin and respiratory sensitizers, as well as carcinogens.
