Iron Inoculation Methods: Part Three :: Total Materia Article

Inoculation is a method of controlling the chemical characteristics of cast iron alloys. Gray iron is composed primarily of iron, carbon and silicon. Free or uncoined carbon in cast iron is called graphite. The degree to which graphite growth is controlled during cast iron solidifiion determines the predictable end qualities of the castings.
