What is aluminum? About the name and formula of its ore. and properties of aluminum

What is Aluminum in hindi:- welcome my website- iticourse.com Friends I have written in this post What is aluminum? And what are its properties and demerits, etc. have been told about it.

What is aluminum?

It is a light and soft metal of white or white gray color. Its main ore is bauxite. On separating aluminum oxide from this ore, a material called alumina is obtained. And this alumina is converted into pure aluminum by electrolytic method.

properties of aluminum

1. Its melting point is 660°C.
2. Its boiling point is 1800°C.
3. Its electrical conductivity is 75%.
4. It is a light metal. And its relative density is 2.7.
5. Its tensile strength is about 1 M-ton/cm.
6. Its electrical resistivity is 2.65 micro-ohm cm.
7. It becomes brittle at temperatures above 150°C.
8. It is a soft, ductile and malleable metal. It can be drawn as wires and rolled as thin sheets.
9. It is a good conductor of heat and electricity. And after copper, it is used to make electric wires.
10. There is no effect of the atmosphere on it.
11. A thin layer of oxide quickly accumulates on its surface, causing its luster to lighten.
12. Aluminum is 98% to 99% pure. And the rest or the remainder is silicon, copper and trace amounts of iron.
13. Air does not affect aluminum at normal temperature.
14. There is no effect of pure water on it, but it is protected by sea water or impure water.
15. Brazing and soldering operations cannot be performed on it.

demerits of aluminum

1. high cost of production look She goes.
2. Adding copper to it reduces its strength or strength.
