    Ferrochrome - Wikipedia

    Ferrochrome, or Ferrochromium (FeCr) is a type of ferroalloy, that is, an alloy between chromium and iron, generally containing 50% to 70% chromium by weight.. Ferrochrome is produced by electric arc carbothermic reduction of chromite.Most of the world's ferrochrome is produced in South Africa, Kazakhstan and India, which have large domestic chromite resources.
