Aluminium
Density: 2.700 kg/mm3
Tensile strength: 700 Mpa (60 kg/mm2)
Young's modulus (E) = 70,000 MPa
Like all metals, it is an excellent conductor of heat and electricity. It also has a very low density for a metal.

Well aluminum is used as you probably know to build planes. It has a low density, it's melting point is about 660 degrees celsius and it's boiling point is 2467 degrees celsius. It's atomic number is 13 and it's Atomic Mass is around 27 g. It has a resistance to oxidation and is extracted from it's ore by electrolysis. This method is very expensive as it uses lots of electricity but is the best way to extract it. Aluminum is quite reactive which is why it uses electrolysis.

Is aluminium a pure metal?
Aluminium is generally considered as a metal, but it shows some properties of metalloid also.
Why Aluminium is called amphoteric metal?
Aluminium oxide is called Amphoteric oxide because it has both acidic and basic properties. Basic property: Al2O3 + H+ ----> Al3+ + H2O Acidic properties: Al2O3 + OH- + H2O----> [Al(OH)4]-
Why is that a piece of aluminium foil exposed to moist air does not corrode even though aluminium is more reactive than iron which easily rust?
Aluminium reacts very rapidly with the oxygen in the air to form a thin film of aluminium oxide covering the entire surface of the aluminium in the foil. This surface is invisible to the eye. Aluminium oxide is very resistant to chemical processes, like corrosion. It protects the aluminium underneath very well, so aluminium does not corrode in moist environments. If the aluminium is scratched, an new aluminium oxide film forms immediately, protecting the scratched part. Iron does not form a protective skin, because iron oxide has different chemical properties to aluminium oxide and is not able to protect the iron.
What is diagonal relation between boron and aluminium?
diagonal relationships are shown by elements in periodic table with same charge to radius ratio, i.e. same polarizing power. important examples are beryllium and magnesium, boron and aluminium, carbon and silicon. diagonal relationship leads to "mimicking" of chemical properties, i.e. beryllium will show properties of magnesium anomalous to its group behavior, for instance formation of nitrites. similarly, boron will "mimic" aluminium and show properties like formation of amphoteric oxides. also boric acid is not a protic acid as it gives H+ only in water, just like aluminium.(B(OH)3+ H2O=>B(OH)4-)
Why is aluminum a suitable material to use in making cans based on its physical and chemical properties?
Aluminium is now cheap, easily machined, has a low density and is resistant to corrosion.
What are the properties of magnalium?
magnesium and aluminium <3
What is the properties and is uses of copper aluminium iron and steel?
copper aluminium iron and steel is an excellent conductor of electricity and heat is one of the properties of copper aluminium iron and steel and it is used in conducting electricity.
Is aluminium is metal?
Aluminium is generally considered as a metal, but it shows some properties of metalloid also.
What are the chemical properties of aluminium in mobile phones?
fried chicken
What are the physical properties of aluminium?
thats what im trying to find out!
Aluminum is properties or not?
Aluminium is very versatile. Some of it's properties include lightweight, conducts electricity etc
What happen when you change the chemical property of aluminium?
The chemical properties cannot be changed; only after a chemical reaction the products have new chemical properties.
Why is an aluminium alloy stronger?
Added alloying (Cu, Mg, Mn, Zn, Si, Zr etc.) metals have the special role to improve mechanical properties of aluminium.
What properties applies to aluminum and not iron?
Aluminium is paramagnetic, iron is ferromagnetic Aluminium has a low density, iron is more dense Aluminium is not corroded in water, iron is easily corroded The hardness of aluminium is lower The price of aluminium is greater The melting point of iron is significantly greater The thermal and electrical conductivity of aluminium are more important Iron has a greater chemical reactivity ................................................................... etc.
Why are alloys so strong?
Alloys are so strong because they will take properties from both metals, such as when you alloy Titanium and Aluminium. Aluminium will get stronger because the forces that titanium once used to attract each other is now used to attract the aluminium
