It's weak because it has lost all it's electrons due to oxidation.
The name of pure iron is just "iron." When iron is in its pure form, it consists of iron atoms without any other elements or impurities mixed in.
Pure iron is rarely found in its pure form in nature because it readily reacts with oxygen to form iron oxide (rust). However, iron can be purified through industrial processes to obtain pure iron for various applications.
Iron is an element, so it is a pure substance.
Iron is a pure metal element when in its elemental form. However, it is often used in alloys, such as steel, where it is combined with other elements to enhance its properties, such as strength and corrosion resistance.
Iron sulfide is a pure compound. It can be as in aqueous medium too as a solution.
It is because the iron is not strong enough to be able to handle the pressures that steel can. Pure iron is to soft and weak to be of any use and the iron from the blast furnace has too much carbon in it to be useful. That is the real reason

Pure iron is homogeneous.
Steel is very resistant to corrosion. It is hard and strong. It is resistant to stretching, depending on the type of steel; low-alloy steel and nickel steel. Steel is maleable, but not 'soft' like pure iron, iron is much more useful when in the form of steel. Pure iron is weak, too soft to be used in construction or for any building purposes.
Weak
Iron can rust. Actually it is because the iron is not strong enough to be able to handle the pressures that steel can. Pure iron is to soft and weak to be of any use and the iron from the blast furnace has too much carbon in it to be useful. That is the real reason

Kinda-sorta. Pure iron is comparably soft and weak, so what's usually used is steel alloys. You start with iron, add a dash of some other metals and some clever treatments and you get steel, which is stronger.
If it is pure iron then by definition there is no carbon or anything else present in it, just iron.
Pure iron is rarely used; frequently iron alloys or coated iron are more important.
Steel is made partially out of Iron, and no, they are not weak unless you stick'em up your anus
Iron is a pure substance. It's an element (Fe) and a bar of Iron is no mixture. If it was pure iron, then by definition it would be pure. However iron is rarely pure, it is usually in alloy with something.
