because it is cheaper
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 is rarely used in in its pure form for construction due to the ease with which it corrodes. However, it is frequently used to make steel which is then widely used on construction sites for things like girders.
Carbon is used to extract iron from its ore because carbon is a powerful reducing agent that reacts with the iron oxide in the ore to form carbon monoxide. This carbon monoxide then reacts with the iron oxide to form pure iron, while carbon dioxide is produced as a byproduct. This process, known as the blast furnace process, allows for the efficient extraction of iron from its ore.
One reason is that gold is considerably denser than iron and therefore sinks more consistently to the bottom of a shaken pan. Another reason is that iron rarely occurs in nature in elemental form, while gold relatively often does occur naturally in elemental form.
Aluminum is rarely used in it pure form in common sheet. There is usually at least some silicon and copper as additives to control certain properties of the metal "mixture".
Pure iron is rarely used; frequently iron alloys or coated iron are more important.
Pure iron is not a strong as steel and it is also prone to corrosion in the form of rust.

Nothing, Iron is a pure substance, an element. However, it can be used to make many things, form nails, to pokers, to bridges.
we get it from reacting it in a blast furnace firstly we react oxygen and carbon coke to form carbon dioxide which then reacts further with the coke to form carbon monoxide which then reacts with oxygen from the iron oxide to form carbon dioxide and pure molten Iron. And we use it occasionaly in medicine as iron supplements or in anylytical chemistry.
Strictly speaking, we rarely use pure iron, particularly not in tools. Mix in a Little of some other stuff, like coal(carbon) Molybdenum, Chrome, Nickel etc you get a falmily of Alloys called steel. Steel is stronger than pure iron and more likely to be used in "iron" Tools.
Pure aluminium is expensive.

Carbon is commonly used to remove oxygen from iron oxide during the process of steelmaking. The carbon combines with the oxygen in the iron oxide to form carbon dioxide gas, leaving behind pure iron.
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.
Alloys are not used instead of pure metals when the desired properties of the pure metal are specific, such as in cases where high electrical conductivity or chemical purity is required.
