Presence of high phosphorous in cast iron increases its____________________?
Correct answer: C. Fluidity
- A. Shrinkage
- B. Melting point
- C. Fluidity
- D. Tensile strength
Explanation
Phosphorus improves the fluidity of molten cast iron, allowing it to fill thin and complex mould sections. Excess phosphorus can make the solid casting brittle, but it does not primarily increase tensile strength.
