Chromium (Chromium), chemical symbol Cr, atomic number 24, belongs to group VIB in the periodic table of elements, the name of the element comes from Greek, the original meaning is "color", because the compounds of chromium have colors. The elemental substance is steel-gray metal, which is the hardest metal in nature. The content of chromium in the earth's crust is 0.01%, ranking 17th. Native chromium in free form is extremely rare and is mainly found in crocoite
Chromium has excellent properties such as hard and brittle, corrosion resistance, etc., so it is widely used in metallurgy, chemical industry, cast iron, refractory and high-end technology and other fields. Metal chromium is used as an additive for aluminum alloys, cobalt alloys, titanium alloys, high-temperature alloys, and resistance heating alloys.
