Production Process. Ferrochrome (FeCr) is a corrosion-resistant alloy of chrome and iron containing between 50% and 70% chrome. Ferrochrome production is essentially a carbothermic reduction operation taking place at high temperatures. Cr Ore, an oxide of chromium and iron, is reduced by coal and coke to form the iron-chromium alloy.
