Aluminium Tempers and Conditions

The hardness and strength of a finished grade of aluminium can be determined by the final heat treatment process. The aluminium temper / condition is usually defined by a series of letters and numbers immediately after the grade, for example 6082 T6 .

Extrusion tempers are defined by their thermally treated designation beginning with ‘T’ and flat products are either ‘O’ or begin with ‘H’.

• O - Annealed (fully soft)
• H - Strain Hardened / Cold Worked
