Aluminum (Al) is a lightweight, silvery-white metal widely used in electrical, construction, and industrial applications.
Basic Properties
* Chemical symbol: Al
* Atomic number: 13
* Appearance: Shiny, silver-colored metal
* Density: Low (about one-third the weight of steel)
* Melting point: ~660°C
Key Characteristics
1. Lightweight
Aluminum is very light, making it easy to transport and install, especially in overhead electrical lines.
2. Good Electrical Conductivity
It conducts electricity well (about 60% of copper), but because it is lighter and cheaper, it is widely used in power cables.
3. Corrosion Resistance
It naturally forms a thin oxide layer that protects it from rust and corrosion, even in harsh environments.
4.Non-Magnetic
Aluminum does not attract magnets, which is useful in electrical and electronic applications.
