Key characteristics of aluminium:

Silvery-white appearance: It has a bright, metallic sheen.

Lightweight: It is relatively light compared to other metals, with a density of 2.7 g/cm³.

Ductile and malleable: It can be drawn into wires or rolled into thin sheets.

Excellent electrical and thermal conductor: It conducts electricity and heat well.

Corrosion resistant: A thin layer of oxide (Al2O3) forms on the surface, protecting it from further corrosion.

Non-magnetic and non-sparking: It is not attracted to magnets and does not spark when struck.

High strength-to-weight ratio: When alloyed, it can become stronger than steel.

Versatile: It can be easily formed, machined, cast, and extruded.

Recyclable: It can be recycled multiple times without losing its properties.
