IS ALUMINIUM A METAL
Aluminium is a chemical component that is indicated by Al, atomic number 13. Aluminium has less thickness as compared to all group members. It is greatly attracted to oxygen and when oxygen came, it forms a defensive layer of oxide on its exterior. By vision, aluminium just looks like silver as its color and capacity of returning the light are the same. Aluminium is soft, solenoid and malleable. It contains only one firm isotope i.e. AL-27 that makes it the 12th common atom in the universe. Aluminium exists in the 3rd group of the periodic tables in the p-block. Electronic configuration of aluminium is 1s-2, 2s-2,2p-6,3s-2-3p-1. At standard conditions, Al is solid and melts at a temperature of 933.47K (660.32 C, 1220.58F). Its boiling point is 2743K. Chemically, in boron group, aluminium is a weak metal because it is common for the group.
Properties
Chemically and technically, aluminium is metal as there are other metals such as brass, steel, copper, zinc, lead or titanium. Its thickness is very less so it can be melted because of the low melting point. Its color is silvery white. Aluminium is commercially produced from Bauxite. Although aluminium is not that strong metal but when it allows with other metals it makes it more stronger than ever.
Corrosion resistance
Naturally, when aluminium exposed to air it generates the defensive layer of oxide which guards aluminium to not in contact with the outside environment. It is a very useful application as when it undergoes corroding substances as in cabins and in the tires of motorcycle, car buses etc. Commonly, alloys of aluminum are less defensive against corrosion than immaculate aluminium other than mg-Al alloys.
Lightweight
Aluminium is a very light-weight element as its weight is 2.7g/cm3. This is third to that of steel. Al uses in the vehicles i.e. in tyres and there also it reduces the weight and consumption of energy is also less. This also lessens the sound.
Thermal and electrical conductivity
Al is a great conductor of heat and electricity. In relation to its low weight, it is actually double good as a conductor as compared to copper, just because of this reason Al has become an instant choice for large power transmission lines. It also acts as a heat exchanger for many devices or application that needs to remove the heat instantly e.g. in LED lights.
Reflectivity
Aluminium is an element that returns visible light and heat. Because of its lightweight, it is an ideal element for reflecting the light. For example rescue blankets and ■■■■■■■■ of light. Cold roofs are also made in which aluminium is used and it reflects 95% of sunlight away from the roof and as a result in summer people in that cold roofs do not get irritated.
Ductility
Al is malleable as it can re-shaped because of its less melting point and thickness. It can also be prepared in a melted state. This property allows the products to be formed perfectly. Even if wires, rods, tubes, geometrical configurations, tubes, rods, or wires it is up to them all.
Impermeable and odorless
As we know the aluminium has less amount of thickness but it is very long-lasting and does not allow anything to affect as it is impermeable and does not allow any smell and taste to come in contact with aluminium foil. In an addition, aluminium itself is not harmful and does not contain any smell so it can easily use for the packing of fragile products i.e. food.
Non-magnetic
As aluminum is not magnetic, that makes it more useful for electrical coverings in computer tasks, and also in a magnetic housing
Non-toxic
Aluminium is not harmful as it is used to make frying pan and all the kitchen products i.e. utensils, pressure cooker without any panic. The kitchen products can be easily cleaned and do not pollute the food product at any period.
Sound and shock absorber
Aluminium is a great absorber of sound as it is used for making ceilings that are soundproof. Because of its shock absorber quality it is used in automobile bumpers.
Non-sparking
Aluminium does not give any spark when it comes in contact with itself and any other substances i.e. non-ferrous metals.
Recyclability
100% Aluminium can be recycled. For recycling purposes, only 5% of energy is required to start a reaction. This process does not need any cost
Summary
Aluminium is a silvery-white metal. Aluminium is malleable and soft that’s why can be reshaped. Its thickness is very low. Aluminium properties are corrosion resistant, light weight, thermal and electrical conductor, reflectivity, ductility, impermeable and odorless, non-magnetic, non-toxic, sound and shock absorber, non- sparking, recyclability etc.
Aluminium is used in power lines, window frames, kitchen utensils, electronics consumer, components of air craft, components of space craft, high rise buildings
FAQ
1. Is aluminium is stronger than steel?
The weight of aluminium is one-third of steel. The important parts of can be mad more thick as it has less density and light weight. But aluminium can be mould in stronger positon than any other steel as we can increase the thickness of it.
2. Why do Americans say aluminum?
All this started when a hesitant British Chemist discovered the new name which was aluminum in 1908. So when he was writing the book “elements of chemical philosophy” in 1812 he used the word aluminum instead of aluminium. That’s why all Americans use this word today.
3.Is aluminium more expensive than gold?
Aluminium is the most ample element on this earth that is why it is not at all costly. In past it used to be expensive than gold but now it is the cheapest and most common chemical element in this universe as it can bond with every element easily.
4. Is aluminium ductile?
Al is malleable as it can re-shaped because of its less melting point and thickness. It can also be prepared in a melted state. This property allows the products to be formed perfectly. Even if wires, rods, tubes, geometrical configurations, tubes, rods, or wires it is up to them all.
5. Aluminium is lightwight?
Aluminium is a very light-weight element as its weight is 2.7g/cm3. This is third to that of steel. Al uses in the vehicles i.e. in tyres and there also it reduces the weight and consumption of energy is also less. This also lessens the sound.
