ALUMINUM ALLOY DESIGNATIONS

What is an Aluminum Alloy

An aluminum alloy is a chemical composition where other elements are added to pure aluminum in order to enhance its properties, primarily to increase its strength. These other elements include iron, silicon, copper, magnesium, manganese and zinc at levels that combined may make up as much as 15 percent of the alloy by weight.  Alloys are assigned a four-digit number, in which the first digit identifies a general class, or series, characterized by its main alloying elements.

Additional heat treatment is important for restoring or modifying the original strength characteristics of the material, for example after its hot forming or welding, when there may be up to 50% loss of strength in the temperature zone, especially when temperatures exceed 200 ° C. The strength characteristics are at the mean values of this class of silicon and magnesium alloys which support its ability to harden. The EN AW 6060 alloy is suitable for surface treatment by anodic oxidation with the expected result also for the category of decorative applications.

HEAT TREATMENT TEMPERS

Alloys in the 2xxx, 6xxx and 7xxx groups can be strengthened by a heat treatment process. The aluminum is heat treated by carrying out a solution treatment process, in which the metal is heated to an elevated temperature followed by rapid cooling, then a precipitation hardening process (or “aging” process). The tempers are designated by –T followed by a digit. Some common –T tempers are as follows:

  • T3 Solution heat-treated, cold worked, and naturally aged: Applies to products that are cold-worked to improve strength after solution heat-treatment, or which the effect of flattening or straightening is recognized in mechanical property limits.
  • T4 Solution heat-treated and naturally aged: Applies to product that are allowed to age harden at room temperature following a solution treatment.
  • T6 Solution heat-treated and artificially aged: Applies to products that are reheated to a low temperature following a solution treatment. This allows the metal to achieve its highest heat-treated strength level.
