· Download reference work entry PDF. Ferronickel is a ferroalloy consisting of nickel and iron. It is mainly used as a nickel additive for steelmaking, for the production of stainless steel and heat-resistant special steel, as well as low-alloy cast iron and cast steel. The addition of nickel can improve the bending strength and hardness of steel.
