6082 Aluminum Forging

Aluminium alloy 6082 is a medium strength alloy with excellent corrosion resistance. It has the highest strength of the 6000 series alloys (6061, 6063, 6082, etc). Alloy 6082 is known as a structural alloy. As a relatively new alloy, the higher strength of 6082 has seen it replace 6061 in many applications, such as cable lugs. The addition of a large amount of manganese controls the grain structure which in turn results in a stronger alloy.

6082 aluminum forging
An attractive combination of strength and formability, corrosion resistance and recyclability has made the age-hardening EN AW 6082 one of the most popular aluminum forging alloys. 6082 aluminum forgings are thus used extensively in automotive suspension components and other applications. The conventional manufacturing cycle starts with the casting of 6082 billets that are subsequently extruded into smaller diameter forging stock. The relatively higher temperatures generated by frictional heating and high strains introduced at the surface during extrusion encourage recrystallisation and produces a heterogeneous structure with fully recrystallised small grains at the surface, fibrous grains at the centre. Hence, the surface of the forged 6082 components inevitably undergoes grain growth once exposed to high temperatures during the solution heat treatment. An attempt was made in the present work to identify an alternative process to achieve a homogeneous section structure with no evidence of coarse grains across the section, which in turn will ensure a better fatigue performance and a longer service life.
