Cast iron generally has low tensile strength but excellent compressive

1.	Cast iron generally has low tensile strength but excellent compressive strength.(a) True(b) FalseThis question was posed to me at a job interview.My question is from Cast Irons topic in division Foundry Introduction & Materials of Casting-Forming-Welding II
Answer» Correct choice is (a) True The best explanation: Cast iron is normally of nonmalleable and brittle nature which defines that, it is not easy to bend or stretched the casting into any shape due to low tensile strength. Cast iron parts TEND to fracture by little of deformation, but cast iron has excellent COMPRESSIVE strength which highly REQUIRED in MAKING of structures of buildings and bridges.
