The coordination number of such compounds varies, but generally Al sublimes (with cracking) at 1,291 °C (2,356 °F).

With heavier halides, the coordination numbers are lower.

Heating the hydroxides leads to formation of corundum.

These materials are prepared by treating aluminium metal with the halogen, although other methods exist.

Aluminium carbide (Al) is made by heating a mixture of the elements above 1,000 °C (1,832 °F).

The pale yellow crystals consist of tetrahedral aluminium centers.

The yield strength of pure aluminium is 7–11 MPa, while aluminium alloys have yield strengths ranging from 200 MPa to 600 MPa.

Aluminium has about one-third the density and stiffness of steel. Aluminium atoms are arranged in a face-centered cubic (fcc) structure.This corrosion resistance is greatly reduced by aqueous salts, particularly in the presence of dissimilar metals.
