Graphite, while also composed of carbon, has an entirely different crystal structure, and different uses. Graphite is used as an electrical contactor (a brush) in electrical motors. It makes a great dry lubricant for things like locks, and when mixed with clay, forms the lead for ordinary pencils.
In spherical form, the graphite exerts a minor influence on the properties of the steellike matrix because in that form the graphite-to-metal contact area is at a minimum. It is relatively economical to produce and finds application in many industries. Ductile iron is similar to other high-carbon, high-silicon alloy with respect to corrosion resistance, sliding wear, and machinability except insofar as the shape of the graphite alters these characteristics.
