Aluminium (13)
- Almost all metallic aluminium is produced from the Ore Bauxite (AlOx(OH)3-2x).
- It also occurs in the minerals Beryl, Cryolite, Garnet, Spinel, and Turquoise.
- It is the third most abundant element (after oxygen and silicon), and the most abundant metal in the Earth’s crust.
- Aluminium is remarkable for the metal’s low density and for its ability to resist corrosion due to the phenomenon of passivation.
- It is nonmagnetic and does not easily ignite.
- Has about 1/3 the density and stiffness of steel.
- Aluminium is a good thermal and electrical conductor, having 59% the conductivity of copper.
