Cast Iron Properties
Cast iron is a group of iron-carbon alloys with a carbon content greater than 2%. It has several unique properties that make it suitable for various applications. Let's discuss the given statements one by one.
Poor Ability to Damp Vibrations
Cast iron has poor ability to damp vibrations. It is a brittle material and has a low modulus of elasticity, which means it cannot absorb vibrations. As a result, it is not suitable for applications where vibration damping is critical, such as machine tool bases, engine blocks, and crankshafts.
Higher Compressive Strength
Cast iron has higher compressive strength compared to steel. Steel has a tensile strength that is higher than cast iron, but cast iron's compressive strength is higher. This makes cast iron suitable for applications where compressive loads are high, such as in columns, pipes, and machine bases.
Suitable for Permanent Deformation
Cast iron parts are suitable where permanent deformation is preferred over fracture. Cast iron is a brittle material and does not have good ductility. Therefore, it cannot undergo significant plastic deformation before fracturing. However, it can undergo permanent deformation before fracture, which makes it suitable for applications where permanent deformation is preferred over fracture, such as in gear teeth, piston rings, and cam followers.
Conclusion
In conclusion, statement 1 is correct, statement 2 is correct, and statement 3 is incorrect. Cast iron has poor ability to damp vibrations, higher compressive strength compared to steel, but it is not suitable for applications where significant plastic deformation is required.
