Across the world, 金属 (Jinshu 
, 金属 ) is a rare predominantly masculine, but scarcely female first name. The first name 金属 is characteristic of Japan, where it is a rare male name, China, where it is a very rare mostly boy's, but infrequently female name, and the United States, where it is an extremely rare epicene name. Not in comparison with a country's population, it most frequently occurs in Japan, China, and India. Very seldom, 金属 is the last name as well as the forename.
