Tokushichi Mishima (三島 徳七, Mishima Tokushichi, February 24, 1893 – November 19, 1975) was a Japanese metallurgist and inventor. He discovered that aluminum restored magnetism to non-magnetic nickel steel. He invented MKM steel, which was an extremely inexpensive magnetic substance that has been used in many applications. It is also closely related to the modern Alnico magnets. He later became a professor at the Tokyo Imperial University. After his death, his remains were buried in the Tama Cemetery in Tokyo.
