MKM steel, an alloy containing nickel and aluminum, was developed in 1931 by metallurgist Tokushichi Mishima (三島徳七). While conducting research into the properties of nickel, Mishima discovered that a strongly magnetic steel could be created by adding aluminum to non-magnetic nickel steel.[1]
Characteristics
The developers claim MKM steel is tough and durable, inexpensive to produce, maintains strong magnetism when miniaturized and can produce a stable magnetic force in spite of temperature changes or vibration. MKM steel is similar to Alnico.[citation needed]
Acronym
MKM is an acronym for Mishima Kizumi Magnetic, 'Kizumi (喜住)' being the inventor's childhood surname.[citation needed]
