Chromium Statistics and Information

Chromium (Cr) has a wide range of uses in metals, chemicals, and refractories. It is one of the Nation's most important strategic and critical materials. Chromium use in iron, steel, and nonferrous alloys enhances hardenability and resistance to corrosion and oxidation. The use of chromium to produce stainless steel and nonferrous alloys are two of its more important

Chromium Chemistry

The oxide can be reduced by aluminium (aluminothermic process) or silicon: Cr 2 O 3 + 2Al → 2Cr + Al 2 O 3 2Cr 2 O 3 + 3Si → 4Cr + 3SiO 2 The main use of the chromium metal so produced is in the production of nonferrous alloys, the use of pure chromium being limited because of its low ductility at ordinary temperatures.
