In ductile iron, the graphite form is spheroidal, or nodular; in cast iron, it is in a flake form. The spheroidal or nodular form of graphite found in ductile iron is accomplished by adding an inoculant, usually magnesium, to the molten iron during the manufacture process.
Willman Industries is a large, independent, cast iron foundry, located in Cedar Grove, 40 miles north of Milwaukee, Wisconsin. We produce all types of grey iron castings and ductile iron castings including Austempered Ductile Iron, Hi-Sil Moly and a full range of Meehanite grades.
Willman's Ductile Iron Foundry produces a family of cast graphitic irons that are high strength, resistant to shock, and with high ductility greatly exceeding standard grey irons and with properties similar to many high grades of steel, plus resistant to fracture even when bent, twisted or deformed.
Ductile iron, also known as ductile cast iron, is a type of graphite-rich cast iron alloy for iron castings. Ductile Iron castings are produced for applications requiring strength, toughness, good machinability, and low cost. Ductile Iron contains spheroidal (nodular) shaped graphite, is higher strength than Gray Iron, and weighs about 10% less ...

As the iron travels down the molding line, the temperature gradually decreases from about 1,200 to 900 degrees Fahrenheit. Temperature at this stage varies based on the size of the casting as well as the molding rate. At the end of the mold line, castings enter a shakeout process where the molds are shaken off and the sand is recycled for reuse.
Spheroidal graphite cast iron is a fancy way of saying "ductile iron." For a full description of this material, you can visit our "What is ductile iron" page. These castings are also known as S.G. iron castings or just S.G. iron. The fancy name "spheroidal graphite cast iron" comes from the make-up of ductile iron.
Ductile iron, also known as ductile cast iron, nodular cast iron, spheroidal graphite iron, spheroidal graphite cast iron and SG iron, is a type of graphite-rich cast iron discovered in 1943 by Keith Millis. While most varieties of cast iron are weak in tension and brittle, ductile iron has much more impact and fatigue resistance, due to its nodular graphite inclusions.

Ductile Iron Casting. Ductile iron, a synthetic metal material that was invented in the middle of the twentieth century, is one type of iron used to make cast iron.The cast iron process involves melting down the iron and metal materials that make it ductile, which can be cerium, magnesium or yttrium.
The purpose of standard specifications for Ductile Iron castings is to provide a body of information which can be used with confidence by both designer and foundry to select, define and agree upon a set of specific properties which will ensure that the castings meet the intended use of the designer. ... complicate the casting process and ...
