Cast iron mainly includes grey cast iron, ductile cast iron and malleable cast iron. As for ductile iron, it has very wide application, such as Pressure pipes and fittings, Automotive applications, Agriculture, road and construction applications, General engineering applications. As for the specific application of ductile iron, grey iron and malleable cast iron, please refer to the links below.
Ductile iron typically has a dark grey color, similar to that of cast iron. It may also have a slight metallic sheen when freshly cast.
Cast iron, is one example of a non-ductile metal. Unlike ductile metals, copper, steel, aluminium - cast iron is too brittle to be reworked.
Malleable cannot be broken like a cast fitting can be and normally malleable fittings / pipe do not have a seam +++ Its full name is Malleable CAST Iron - it is cast as "ordinary" cast-iron but is a lot less brittle. It is an important material combining some of the properties of cast-iron with those of mild-steel.
Well . . . there is cast iron, ductile iron, steel, copper, galvanized steel, PVC, ABS, concrete, fiberglas . . .

Mechanical Properties of Ductile Iron. Ductile iron is characterized by having all of its graphite occur in microscopic spheroidsCast iron is formed by remelting pig iron, and is useful for a variety of engineering purposes.Properties and Uses of Iron. Iron is one of the three magnetic elements (the others are cobalt and nickel). Cast iron is very brittle (it cracks easily
Mild steel
Yes, ductile iron is conductive. Its electrical conductivity is similar to that of gray cast iron due to the presence of graphite in its microstructure. This makes it a good choice for applications where electrical conductivity is required.
As for the most of rough surfaces of cast iron, the color is grey. Such as normal grey cast iron and ductile iron. The ductile iron will be more white than grey cast iron. There are few types of vermicular cast iron, which are black. The white cast iron will show white color. So, cast iron has different color, such as grey, black, white according to different types. However, most of cast iron castings need surface coating, such as painting or electroplate, so they will show different colors than their own.
