SUOYI High quality Metal Cr Chromium Blocks refractory semiconductor chip
Chromium, chemical symbol Cr, atomic number 24, belongs to Group VIB in the periodic table. The element name comes from Greek, which originally means "color", because chromium compounds have colors. The element is a steel-gray metal, which is the hardest metal in nature. The content of chromium in the earth's crust is 0.01%, ranking 17th. Free natural chromium is extremely rare and mainly exists in chromite. The relative density of pure chromium is 7.15g/cm3, the melting point is 1907ºC, and the boiling point is 2679ºC. The resistivity is 12.7x10-8Ω·m (20ºC).
