The answer to this question is fundamental to Chemistry, and if you can remember and apply this, then you have overcome a hurdle. The answer that pure iron isn't strong enough, that's true and right, but the real question is why is it not strong enough. Where do metals, for example, get their strength? They get their strength from the bonds between the atoms that make up the molecules, that make up the metal. Some bonds are very strong, some are weak. You can measure what kinds of effort that it takes to break the bonds. Iron rusts and breaks up pretty easily over time. Steel is much better.

If a soft iron core is Inserted into a solenoid will the strength of magnetic field produced by it change?
It has been found that if a soft iron rod called core is placed inside a solenoid, then the strength of the magnetic field becomes very large because the iron core is magnetized by induction The core of the electromagnet must be of soft iron because soft iron loses all of its magnetism when current in the coil is switched off or stopped
Where are alloys found?
Metal alloys are used whenever a pure material does not have the desired characteristics. For example, pure gold is beautiful, but relatively soft and does not keep its shape well. A gold alloy is just as pretty, but is hard enough to resist dents. Iron is hard, but rusts quickly. Steel, an alloy of iron, carbon and other metals, is harder and more durable.
Is rust magnetic?
Iron Oxide is not magenetic, only pure iron, nickel, cobalt, and steel can be magnetic.
Is iron ore a homogeneous or heterogeneous substance?
Pure Iron is considered as Homogeneous. Whereas, Iron with rust or other impurities is Heterogeneous.
What is an advantage of using alloy instead of pure iron?
Iron as an alloy is stronger and has a higher melting point. It can also be made to be much more resistant to rust (the most resistant alloy being stainless steel). Hence it is preferred to pure iron.Pure iron is quite brittle and very susceptible to rust. Iron alloys maintain the strength of iron and make it more malleable (less brittle) and can also make the alloy resistent to rust.
Why does pure iron have limited usues?
The reason pure iron has limited uses is because it is a soft metal and not very strong.
What is the composition of soft iron gasket material?
The soft iron gasket is pure iron with a carbon content of less tha 0.1 % . The hardness is Br<= 120
How does soft iorn is different from hard iron?
That depends on what you mean - soft iron is usually the name given to iron that is easily magnetised and demagnetised. In which case it is usually very pure. Mecahnically soft and hard irons have different crystal structures and trace impurities, although iron is more correctly known as steel when it is anything but 100% pure iron.
What is made out of iron?
In fact, the golden gate bridge is made out of iron. Also, don't be surprised of iron is an ingredient in your medicine because it is good for you in some cases!
Can you convert iron into wires?
Yes, it can. It's unusual to make anything from pure iron, however, because it is soft, weak and susceptible to oxidation.
What is soft iron hardness?
Pure iron is relatively soft and easily worked (malleable). Iron heated to high temperatures and alloyed with carbon and other elements is called steel, which can be made extremely hard and durable, but not easily worked.
Why is steel superiour to 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.
What is the name of the pure iron?
Pure Iron is called Pure iron.
What type of bridge is the iron bridge?
The Iron Bridge in Shropshire is the world's first bridge constructed entirely from iron.
Why is pure iron not good in terms of structure?
it's too soft(maluable), too heavy and rusts or corrodes.
Why is steel rather than pure iron used to make car bodies?
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
Can you change the shape of iron?
Of course, pure iron is malleable, actually rather soft. Some alloys of iron are very brittle and cannot easily be shaped with everyday household tools.
