Cast iron has____________________?
Correct answer: C. Its elastic limit very close to ultimate breaking strength
- A. High ductility
- B. High malleability
- C. Its elastic limit very close to ultimate breaking strength
- D. Very high tensile strength
Explanation
Cast iron is brittle and undergoes very little plastic deformation, so its elastic limit lies close to its failure or ultimate breaking strength. It consequently has poor ductility and malleability and relatively low tensile strength.
