ISO/TR 15608 Material Group 22.2 such as Aluminium AW-5005 alloy :
Non heat treatable aluminium-magnesium-alloys with Mg ≤ 1,5 %
Features of Aluminium AW-5005 alloy
Compared to unalloyed aluminum, this material exhibits increased strength and high-temperature strength (due to the recrystallization-inhibiting effect of manganese). Al-Mn alloys are easy to form and good for welding. The alloys are atmospheric corrosion resistant, have moderate/high strength, and are not hardenable (by heat treatment). 5005 aluminum material is a medium-strength aluminum alloy material and it has good formability.
This alloys are almost only used as a wrought alloy and is processed into sheets or profiles by rolling or extrusion processes. H34 – Stabilised – A low temperature thermal treatment or heat introduced during manufacture which stabilises the mechanical properties and relieves residual internal stress, plus usually improves ductility.
Applications for using Aluminium AW-5005 alloy
The performance of 5005 aluminum alloy is similar to that of 3 series 3003 aluminum alloy, with moderate strength, good fusion, workability and formability,. This makes it an ideal material for a variety of construction and engineering projects that require continuous exposure to high temperatures such as thermal processing lines.
