ALUMINIUM Al+3 TOXICITY AND ALUMINIUM METAL LIGHTENING THE LOAD

ALUMINIUM Al⁺³ TOXICITY AND ALUMINIUM METAL    LIGHTENING THE LOAD

Toxicity of Al⁺³

It has been supposed for a long time that Al⁺³ is nontoxic for human. Al(OH)₃ is recommended for the  anti-acid treatment for ingestion while Al(SO₄)₃is used for the drinking water treatment. Research has shown Al⁺³ is toxic for patient having kidney failure issue who are unable to excrete the metal. Similarly people with Alzheimer disease have Al salts accumulated on their brain.

ALUMINIUM METAL    LIGHTENING THE LOAD

Aluminium is of group 3 element its physical and chemical properties are responsible for vast application. Aluminium  is a

i)                   Light metal

ii)                High thermal and electrical conductivity.

iii)              Easily machined

iv)              High reflectance

v)                Show resistance to corrosion due oxide layer formation on its surface.

But at the time pure aluminium is a soft metal and due to lack of strength its alloy are prepared . during alloy formation less than 2% other elements are added to Al.

The process of alloy formation and the chemical composition determined the properties of alloy.

Al/Mg Alloy.

The most oldest alloy of aluminium with magnesium which has wide applications has the properties of

i)                    good ductility

ii)                Corrosion resistance.

It also contains traces amount of Si and Fe and has a good strength.

Al/Si Alloy, Al/Li Alloy

Al/Si Alloy has higher density than Al/Li Alloy and is in welding of wires while Al/Li Alloy has high elasticity and when Cu is added to this Alloy it not only  increases its density but also its strength and corrosion resistance ability.

Use in construction

Aluminium Alloy are used to prepare walls, gutters and windows frames and door in construction .Aluminium Alloy has

i)                   Low mass or weight

ii)                High resistance to corrosion

iii)              Good strength

The above three properties are responsible for the extensive use of aluminum alloy in construction.

In transport

In transport there are two major problems  i) weight   ii) fuel consummation

The Al/Cu/Mg Alloy are used in aircrafts while the Al/Cu alloy of aluminium is used in the space vehicles and satellites.

 Industries

In making Cooking utensils, refrigerators bodies, air condition units etc. Aluminium Alloy is extensively used.

Aluminium Bronze
Aluminium in the power form is known as aluminium bronze and is used in the manufacturing of aluminium paint.
