Density of Aluminium
The density of aluminium is about 2,710kg/m3. The density of the alloys of aluminium does not vary widely from this figure ranging between 2,640kg/m3 and 2,810kg/m3.
Aluminium alloy density
Aluminium has a low density, which means it is lightweight and easy to move. For this reason, it is preferred metal choice when building aeroplanes. While being lightweight, the material is also very strong and easy to shape, making it the perfect choice for manufacturing.
Resistance to corrosion
Aluminium forms a thin layer of its oxide on the surface of the metal. This keeps air and water from getting into the metal which causes corrosion. Because of this oxide, the metal is resistant to corrosion making it more reliable.
Another impressive property of aluminium is the fact that it can be recycled 100%. This makes aluminium an environmentally friendly metal and also saves its ore from being depleted. The process of recycling aluminium is low cost and does not deplete the quality and properties of the material.
Electrical and thermal conductivity
In relation to its weight, aluminium is twice as a good a conductor as copper. It is an excellent conductor of heat and electricity and so commonly used in most major power transmission lines.
