A Little Bit About Aluminum

Aluminum is a light silver-white metal with a melting point of 660.37°C, a boiling point of 2467°C, and a density of 2.702g/cm ³. Aluminum is face-centered cubic structure, which has better electrical and thermal conductivity. Pure aluminum is softer. Aluminum is a reactive metal. On the surface of aluminum in dry air, a dense oxide film with a thickness of about 50 angstrom is immediately formed, so that aluminum will not be further oxidized and can withstand water. But aluminum powder burns easily when mixed with air; Molten aluminum reacts violently with water; Many metal oxides can be reduced to corresponding metals at high temperature; Aluminum is amphoteric, soluble in strong bases, but also soluble in dilute acids.
