1.	Which of the following parts are mostly manufactured by using grey cast iron?(a) Pistons(b) Surgical equipment’s(c) Thin sheets(d) Engine blocksThe question was posed to me by my school teacher while I was bunking the class.My question is from Cast Irons topic in section Foundry Introduction & Materials of Casting-Forming-Welding II
Answer» Correct option is (d) Engine blocks For explanation I would say: The FLUIDITY and expandability of MOLTEN grey CAST iron at the time of solidification, due to the FORMATION of graphite flakes, this iron BECOMES ideal for the manufacturing of shrinkage free and intricate castings components like engine blocks. The graphite presence greatly enhances mechanical properties in grey cast iron.
