Aluminium – A Feather Weight Metal

Aluminum also known as Aluminium is a silvery white colored element which is classified under the boron group in chemical table. It’s symbol is Al and is the third most abundant element in earth. Aluminum is not available in native form since it is highly reactive and so is extracted from Bauxite ore using Hall-Heroult extraction process.

Aluminum density
Density of a material is defined as its mass per unit volume.
Mass is also called weight nowadays and it is the quantitative measure of resistance shown by an object to acceleration.
Volume is measure of three dimensional space occupied by an object.

Aluminum’s density is the lowest among the metals. It is well known for is low density and corrossion resistance.Aluminum density is only one third of the density of steel. The numerical value of aluminum density is 2.8g/cm3 or 2800kg/m3.Aluminum density can be further reduced by creating alloys from it.

Why is Aluminum density low compared to other metals?
Though aluminum atoms are arranged in Face Centered Cubic (FCC) structure which has a higher atomic packing factor than the Body Centered Cubic (BCC) structure of Iron or steel , it has lower density than steel due to the lower atomic number(Steel is considered as a light material but Aluminum has only half the number of atoms in iron using which steel is made.). Since the number of atoms are less, the resistance offered by aluminum gets reduced which results in lower density.

* Aluminum is used in aviation industries for the purpose of aeroplane manufacturing. Aluminum is also used in manufacturing of specific parts of other vehicles.
* Used in making foils used for packaging due to its high ductility.
* Used for making alloys which are used for different engineering applications.
* Used as heat sinks in electronics and transmission lines in electrical engineering.

The Density of Aluminum

Aluminum is a light in weight, strong and silvery white colored metal. It has an ‘Al’ symbol and is from the boron group. Besides that this metal under normal conditions is not soluble in water. As much as this metal is light it will sink in water. The density of aluminum stands at 2.7 g/mL which shows that it can sink. Because of its density this metal has a variety of uses as can be seen below.

The most common use of this metal is its uses in the manufacture of cans and foils. Due its properties that involves being made into thin sheets allows this metal to be thinned into aluminum foil and also moderately thicker sheets which are used to make cans.

Most kitchen utensils are made of aluminum, from spoons to cooking pans and also there are plates that are made of aluminum. This is because of its good conductivity of heat and also its untrusting qualities. But to achieve this it is combined with stainless steal.

In most industrial applications that require a light but strong material, aluminum is the best choice. I most storage facilities in such industries it is the only material used in making the storage facilities making it the most sought after metal.

It is also used in the manufacture of electricity wires. Although it has a low electrical conductivity than copper it is commonly used in the electrical transmission lines due to its lightness properties and also its price as compared to copper.

Its alloys with other metals are very vital in the manufacture of modern airplanes and rockets. It is one of the light but strong metals that are commonly used in the airplane factories and rocket making industries. To add on that it is used in the manufacture of planes and rockets because it can not react with air.

In conclusion, the density of aluminum makes this metal one of the metals that has very many uses ranging from industrial uses to domestic uses. This makes it the one of the most sought after metals.

Celcius, it becomes very weak.

Linear expansion – it has a large coefficient of linear expansion.
Machining – it is easily milled, drilled, cut, punched and bent with low energy.
Formability – it is highly formable and this makes it very essential in extrusion. This is

why it is used for making foils and strips.

Conductivity – it is a good conductor of electricity with weight half of similar copper


Reflectivity – it reflects well both visible light and radiated heat.
Screening EMC – tight aluminium boxes screen off electromagnetic radiation.
Resistance to corrosion – when aluminium reacts with oxygen in the air, a very thin layer

of oxide is formed. This layer is dense and protects the metal
from corrosion.

Durability – it is long lasting in neutral and slightly acidic environments.
Non magnetic – it cannot be attracted by any magnet hence it is used in magnet X-ray

devices to shield off interference of magnetic fields.

Zero toxicity – it is the most common element in the earth’s crust after oxygen and silicon and also occurs naturally in food.

These properties of aluminium are what makes it a widely used metal in the world. It’s uses vary from one industry to another in the making of aircrafts bodies because of its light weight ability, lightweight vehicles, ladders for use to ascend on electric or telecommunication poles, drinking cans and roofing materials, greenhouses, window frames, boilers, cookers and cookware, overhead power cables, mirrors, reflectors and heat resistant clothing for fire fighting.

The low density of aluminum once again makes the automotive industry use this element in the making of cars, trucks and other means of transport. By using this lightweight element they are to obtain their fuel efficiency target more easily than they could with iron.

Other uses of aluminum include the aluminum foils that are used in wrapping the food or keeping other things safe from the sunlight. Even that small gum you eat while playing sports is wrapped in that shiny wrapper made out of aluminum. You can easily see how density of aluminum makes it usable for almost anything you can think of. If you don’t eat bubble gum, you must have had a drink at least once in your life. Once again the density of aluminum makes it a perfect choice for beverage industries to pack their beverages in aluminum cans that can be easily recycled later on.

Density Of Aluminum – An Incredible Property

Aluminum is an abundant ferrous metal in nature, which makes up to 8% of the earth’s crust. Aluminum does not occur in free form naturally. It is extracted from rocks, gemstones, minerals and specifically aluminum silicate. Nevertheless, aluminum is mainly extracted form the ore called bauxite. Pure aluminum has many properties such as light weight, odorless, non magnetic, lowest melting point among metals and most importantly low density of aluminum. In addition, aluminum is widely spread around the globe and is also highly reactive. In spite of being most reactive, aluminum is corrosion resistant. Low density of aluminum makes it a very precious metal in today’s world where every manufacturing sector is working to produce ducts with lowest possible density, weight and volume.

Since aluminum is extracted conveniently, the epoch of inexpensive aluminum started. Initially, ALCOA (Aluminum company of America) begun with producing 25 kilograms of Aluminum, and by 1990 the company achieved the benchmark by producing 41,000 kilograms of Aluminum a day. Today Aluminum is preferred by most manufacturing companies because of low density of aluminum. The numeric value of density of aluminum is 2.72 grams per cubic meter. Because of this property, vast application of aluminum lays in cans, foil papers, kitchen utensils, aircrafts, rockets etc. Secondly, when aluminum is mixed with other metals, it becomes stronger than steel.

Because Aluminum is naturally composed as low density of Aluminum, it is economically transported. Furthermore, this property also facilitates the user with easy handling of the equipment. Additionally, on the basis of light weight and low cost, aluminum is a better conductor of heat as compared to other metals. This also makes aluminum use relevant in heat exchangers. However, aluminum is also blessed with inflammability property, which makes it more versatile. This is not enough, density of aluminum is also responsible for its properties such as malleability and ductility. It is also environmental friendly because it does not produce toxic fumes even at high temperatures.

Density of aluminum is about one third of steel, which make is preferable in the manufacturing of aircrafts. Aerospace, Aviation, automobile and food industry also makes use of aluminum because of its light weight. Aluminum is 20% to 40% lighter then steel, but thrice expensive than steel. Moreover, low density of aluminum has advantage of copper electricity transmission lines, even though its electric conductivity is only about 65% of that of cooper. Last not but the least, this fantastic property of aluminum enables less energy consumption.
