FAQ: What Are the Commonly Used Aluminum Tempers?

Aluminum temper refers to the specific condition or state of aluminum alloy after it has undergone a heat treatment process or cold working. Different tempers are achieved by applying specific combinations of heating, cooling, and mechanical processes, which result in varying mechanical properties and characteristics of the aluminum.

aluminum Annealing aluminum factory picture

1. O (Annealed): This is the softest temper of aluminum. The material is fully annealed, making it easy to form and work with. It has low strength but high ductility and excellent formability.

2. H (Strain Hardened): The H temper indicates that the aluminum has undergone strain hardening or cold working. The temper is followed by a number, such as H12, H14, H16, etc., indicating the level of strain hardening. Higher numbers indicate greater hardness and strength.

3. T (Thermally Treated): The T temper indicates that the aluminum has undergone a heat treatment process. The temper is followed by a number, such as T4, T6, T651, etc., indicating the specific heat treatment conditions. Different T tempers result in varying levels of strength, hardness, and mechanical properties.

4. F (As Fabricated): The F temper indicates that the aluminum is in its as-fabricated condition, without any specific heat treatment or cold working. It is typically used for products that do not require additional tempering or hardening.

5. W (Solution Heat Treated): The W temper indicates that the aluminum has been solution heat treated to homogenize its microstructure and improve its formability. This temper is often followed by the letter T to indicate subsequent aging treatment.

There are additional tempers that may be specific to certain alloys or applications. It’s important to understand the temper designation and its corresponding mechanical properties when selecting aluminum for a particular application.
