Ductile Iron Casting
Ductile iron casting, also known as spheroidal graphite casting, SG iron casting or nodular iron casting, was developed in 1943 by Keith Mills. This process involves melting and casting ductile iron (iron alloys with controlled microstructures) along with one of the elements that makes it ductile. This is usually either magnesium, cerium or yttrium. Ductile iron castings are not only more ductile than grey iron castings, but also have higher tensile strength than gray iron castings. Because of the high tensile strength and ductility it produces, ductile iron casting is used to a variety of applications in many different industries. These industries include, but are not limited to agriculture, automotive, irrigation,ventilation, hydraulics, and manufacturing.
