Difference Between Iron and Aluminium

The key difference between iron and aluminum is that iron is heavier than aluminum. Iron is a chemical element having the atomic number 26 and the chemical symbol Fe. ... Aluminum is a chemical element having the atomic number 13, and the chemical symbol is Al. It is a silvery-white, shiny metal that resembles iron.

Why is Aluminium better than iron?

This is because extraction of Aluminium from its ore is quite expensive than extraction of Iron from its ore. ... Aluminium is a better conductor of electricity than Iron. Al is also more ductile than iron. In terms of malleability, Aluminium is second among metals.

Is aluminum stronger than iron?

Strength is a factor

Aluminum is sturdy, but it can bend on impact. It is possible to replace the panels, and our method of attaching them makes it a very simple task. Iron though is a tough material. It has natural impact inhibitors, and an iron fence does not bend, break or fall over too easily.

Is Aluminium made of iron?

The most important aluminum ore is bauxite, a rock containing about 52% aluminum oxide with impurities of iron oxide, silica, and titania.

What is the difference between iron and metal?

The primary difference between iron and steel is that the former is a metal, whereas the latter is an alloy. Iron is simply a metal element that occurs naturally on Earth. In comparison, steel is a man-made alloy that's made by mixing iron and carbon together.

Why is aluminum so expensive?

Aluminum is the most common metal in the earth's crust, almost twice as abundant as iron. ... In fact, aluminum became more precious than gold and silver in the 19^th century, because it was harder to obtain.

Is Aluminium stiffer than steel?

Stiffness of a component is a function of both material and geometry. ... This means that for a fixed geometry, a part made out of steel will be three times as stiff as if it were made out of aluminum. In other words, an aluminum part under load will deflect three times as much as a similarly loaded steel part.

What are the weaknesses of aluminum?

Aluminum alloys will warp at high temperatures and unlike steel, do not glow red before melting. Aluminum alloys also feature a lower fatigue limit than steel and will continually weaken with repeated stress. They are rarely used in fabrication applications that require high fatigue rates.

Is Aluminium better than steel?

Even with the possibility of corrosion, steel is harder than aluminum. Most spinnable tempers and alloys of an aluminum dent, ding or scratch more easily as compared to steel. Steel is strong and less likely to warp, deform or bend underweight, force or heat. ... Steel is typically 2.5 times denser than aluminum.

Which is costly Aluminium or steel?

In raw materials costs, aluminium is about three times more expensive than steel, while in terms of conversion costs it is about twice as expensive, MIT said. And in assembly costs, aluminium was 20-30% more expensive than steel.

What are 5 uses of Aluminium?

Below are ten of the most common and useful applications of aluminium in modern society.

1. Power lines. ...
2. High-rise buildings. ...
3. Window frames. ...
4. Consumer electronics. ...
5. Household and industrial appliances. ...
6. Aircraft components. ...
7. Spacecraft components. ...
8. Ships.

Why do Americans say aluminum?

It all began, apparently, when an indecisive British chemist by the name of Sir Humphrey Davy in fact coined the now archaic word "alumium" in 1808. However, referring to the element in his 1812 book Elements of Chemical Philosophy, he would use the word "aluminum", much as Americans do today.

Is Aluminium man made or natural?

Aluminum was born out of science.

Aluminum isn't naturally found in the Earth's crust. It comes from bauxite, which has to be processed to get aluminum. ... Essentially, innovation made this metal possible.As an interesting fact, Danish chemist Hans Christian Oersted first extracted aluminum from alum in 1825.
