Question

1. Which of the following statements is correct?
   1. Pig iron is strong in compression and tension, and it does not rust
   2. Cast iron usually contains low amounts carbon content
   3. Pure iron and wrought iron both are highly resistant to corrosion
   4. Pig iron, cast iron, pure iron, and wrought are all brittle materials

2. Identify the ferrous metal from the list below:
   1. Aluminium
   2. Copper
   3. Iron
   4. Zinc

3. Which one of the following statements is not correct about pig iron?
   1. Pig iron has a very high carbon content, typically 3–4%
   2. Hard but weak and brittle, not suitable for construction purposes
   3. Strong in both compression and tension
   4. It normally needs to be refined into steel or a better grade of iron

Answer 1

Ans 1 : C) Pure iron and wrought iron both are highly resistant to corrosion , due to the fact that pure iron and wrought iron has very low carbon content which makes it highly resistant to corrosion . Therefore this statement is correct .

Ans 2 : C) Iron is a ferrous metal amongst all the options .

Ans 3 : C) Strong in both compression and tension , this statement is not correct about pig iron because Pig iron is strong in compression but not in tension . Therefore this statement is incorrect about pig iron .
