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.

ENAW-5083

Material is distinctive for its excellent burnishing qualities and very good corrosion resistance. It is medium strength with excelent chemical resistance but resists hardening. Cutting tool suitability is low with the material in its soft temper and therefore the application is better suited to a harder material. Weldable with joints of superior corrosion resistant comparable to that of the original material. Very good plasticity in its soft condition. Used for medium tension construction purposes with excellent resistance to attack by sea water.

Use: mechanical engineering, single-purpose machine construction, vessel craft engineering, welded constructions, moulds for foam and rubber materials, prototype moulds, shearing tools, automotive engineering, automotive prototypes: pipes, liquid containers, applications with working compression up to 1,6 MPa in a temperature range from -196 °C to +150 °C, (device components, cisterns and protective casings).

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.
