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

Why copper is not contain any carbon?

Even non ferrous materials are having more ductility compare to MS, and Aluminium and Copper this both are not having any carbon content.

MS>Cu>Al>Ni>Zn>Sn>Pb.

Al>Cu>Ni>Mild steel.
Is this not right ?

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.
