Why cast iron?

@ramesh MS is not more ductile than AL as at izod impact test AL absorb more energy than MS. So AL is more ductile than MS.

Al has the highest ductility because it has high stacking fault energy and low strain hardening exponent.

I guess Fe is having BCC structure where Al is of FCC. FCC structure materials are more ductile than the BCC. Adding carbon in Fe will increase its hardness. So according to these facts Al should be more ductile than MS.
But in practical(Tensile test) MS will have more elongation than Al for the same dimensional specimen. This is somewhat confusing.

Al is more ductile than MS.

Because mild steel elastic modulus is high compared to remaining options.

Because it has very less carbon content. More carbon content became hardness.

Aluminium not have any carbon percent but why is MS?

I believe there is a constant yield value for the above mentioned elements, on consideration its mild steel. It can withstand more tensile force before necking.

Copper & Al are more ductile material than iron.
