Yes iron is very much heavier then plastic.
No, atomically Iron is a heavier element

The two nuclei's are lighter than iron then when they are fused together they will release energy. If the two nuclei's are heavier than iron they will absorb energy when fused.
Elements that are formed in cool stars are heavy but not heavier than iron. (Elements that are heavier than iron are formed in a supernova.)
Iron weighs 0.284 pounds per cubic inch, while cast iron is about 0.25-0.27 pounds per cubic inch, due to how it is made and processed. So pure iron is heavier
