Melting Point:660°C
Boiling point:2327°C
Density: 2.7g/cm
Aluminum is light silvery metal.
Chemical property
Auminum can form a oxide film at the damp air. Aluminum powder is mixed with air is very easy to burn. Molten aluminium can react vigorously with water. It can restore many metal oxide to the corresponding metal at high temperature.
