 3. Tempers

Temper

Description

Applications

F

As fabricated

Forging stock: Maximum formbility

O

Annealed

Forging stock: Maximum formbility

T4

Solution heat-treated and naturally aged

Formability with higher properties than F or O conditions

T5

Cooled from an elevated shaping process temperature and artificially aged

Where highest mechanical properties are not required by end of use(i.e non-structural)

T6

Solution heat-treated and artificially aged

Where highest possible mechanical properties are required

 Notes: 

Extruded products are normally available in the tempers listed above.

Tempers other than those listed may be available upon request.
