There are two basic types of aluminum heat-treatable and non-heat treatable. Each are widely used but their different characteristics impact the final strength of the weld, as these alloys differ in their chemical and metallurgical structure and in how they
Heat Treatable 6xxx Aluminum Alloys Silicon and magnesium are combined with aluminum and heat treated to make a weldable metal that is versatile and possesses moderay high strength. This aluminum alloy has greater corrosion resistance, and will often be used to clad 2xxx series aluminum
Non-Heat-Treatable Alloys The initial strength of alloys in this group depends upon the hardening effect of elements such as manganese, silicon, iron and magnesium, singly or in various combinations. The non-heat-treatable alloys are usually designated,
Aluminium alloys are classified into heat-treatable alloys (precipitate-strengthened) and non-heat-treatable (solid-solution-hardened), which result in different hardness profiles when FSW In aluminium alloys, the heating in HAZ is generally high enough for the recovery of cold work and coarsening of precipitates, which leads to changes in mechanical properties in this

This heat-treatable alloy is claimed to offer automakers greater design flexibility due to its superior formability, strength performance and weight savings for outer and inner applications. Novelis introduces Advanz 6HF - aluminium alloy in
The heat treatable 4xxx series aluminum alloys are most often encountered when involved with the post weld heat treatment of the welded, heat treatable, aluminum base alloys. Typically, the heat-treatable base alloys, such as 6061-T6, lose a substantial proportion of their mechanical strength after
Aluminum alloys come in two distinct heat-treatable and non-heat-treatable. Both basic types help to determine the characteristics of the chemical and metallurgical structure. The different alloys also have a different arc welding process. The strength of non-heat-treatable aluminum alloy comes when alloying aluminum with additional elements. Typically, manganese,
The non-heat treatable alloys depend primarily on cold work to increase strength. Annealing Annealing is applied to both grades to promote softening. Complete and partial annealing heat treatments are the only ones used for the non-heat treatable
