What is the term cast iron?
cast iron. noun. Definition of cast iron (Entry 2 of 2) : a commercial alloy of iron, carbon, and silicon that is cast in a mold and is hard, brittle, nonmalleable, and incapable of being hammer-welded but more easily fusible than steel.
Why is it called a cast iron?
Cast iron is one of the most extensively used alloys of ferrous. It is made from pig iron by the process of casting and hence the name.
What does cast iron evidence mean?
A cast-iron guarantee, piece of evidence, etc. is absolutely certain and can definitely be believed. They are demanding cast-iron guarantees of a fair hearing. Even if one could visualize her as a murderer, she has a cast-iron alibi. They will punish you for being late, unless you’ve a cast-iron excuse.
What is cast iron and its types?
Types of cast iron and their applications
- Grey cast iron. Grey cast iron, or gray iron, has a dark grey fracture colour due to a graphitic microstructure.
- White cast iron. White cast iron has a white fracture colour due to the presence of iron carbide, or cementite Fe3C.
- Malleable cast iron.
- Ductile cast iron.
How is cast iron classified?
Presently the common classification scheme divides cast irons into four basic types. These are (i) white cast iron, (ii) gray cast iron, (iii) ductile cast iron, and (iv) malleable cast iron.
What is the difference between iron and cast iron?
Wrought Iron is iron that has been heated and then worked with tools. Cast Iron is iron that has been melted, poured into a mold, and allowed to solidify. The fundamental distinction between cast iron and wrought iron is in how they are produced.
What are the benefits of cast iron?

What is cast iron microstructure?
Cast irons are a class of ferrous alloys with a carbon content of between 2.0 – 4.5\%; they contain sufficient carbon so that the eutectic reaction occurs during solidification. Cast iron contain contrasting amount of manganese, sulphur and phosphorus. …
Why is cast iron important?
With its relatively low melting point, good fluidity, castability, excellent machinability, resistance to deformation and wear resistance, cast irons have become an engineering material with a wide range of applications and are used in pipes, machines and automotive industry parts, such as cylinder heads, cylinder …
Is cast iron ferrous or nonferrous?
The word ‘ferrous’ comes from the Latin word ‘ferrum,’ which means ‘iron.’ Ferrous metals include steel, cast iron, and titanium, as well as alloys of iron with other metals (such as with stainless steel).
Cast Iron and its Types: Gray Cast Iron: Cast iron which contain carbon in free form, known as Gray cast iron. White Cast Iron: Cast iron in which carbon is present in combined form or in carbide form known as white cast iron. White colour is due to carbide formation. Malleable Cast Iron: This cast iron is obtained from white cast iron by heat treatment process.
How does cast iron differ from wrought iron?
The main differences between cast iron and wrought iron are – Cast iron is iron that is melted and poured into a mold so that it takes the shape of the mold. Cast Iron is brittle, hard and non-malleable. Wrought Iron has a higher tensile strength compared to Cast Iron and can be used in the manufacture of horizontal beams.
What are examples of cast iron?
Types of cast iron and their applications Grey cast iron. Grey cast iron, or gray iron, has a dark grey fracture colour due to a graphitic microstructure. White cast iron. White cast iron has a white fracture colour due to the presence of iron carbide, or cementite Fe3C. Malleable cast iron. Ductile cast iron.
What are the weaknesses of cast iron?
Disadvantages of cast iron It is Prone to rusting It has poor tensile strength Its parts are section sensitive, this is due to slow cooling of thick sections. failure of Its parts is sudden and total, it does not exhibit yield point. It has poor impact resistance Compared to steel it has poor machinability It has High weight to strength ratio It has High brittleness
