| A) Aluminium has the following advantages: |
-
Lightweight and strength .
- Corrosion resistance.
- Easy forming.
- Electrical conductivity.
- Thermal conductivity.
- Non-toxic.
- Non-magnetic.
- Non-sparking.
- Reflectivity.
- Low temperature properties.
- Machining.
- Welding .
Furthermore, through the colour anodizing process, we can get inorganic films on aluminium surface
to produce a finish having corrosion resistant and unchanging colour. |
