ISO/TR 15608 Material Group 22.1 such as Aluminium 3003 alloy:
Non heat treatable aluminium-manganese-alloys
Features of Aluminium 3003 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 and soldering (hard and soft soldering).
Aluminium 3003 alloy is almost only used as a wrought alloy and is processed into sheets or profiles by rolling or extrusion processes. The alloys are corrosion-resistant, have low/moderate strengths for aluminium alloys, and are not hardenable (by heat treatment). Aluminium 3003 alloy is suitable for the manufacture of pressure vessels and piping in accordance with EN 1392 “Aluminum and aluminum alloys – Wrought and cast products – Particular requirements for products for the fabrication of pressure equipment” see list below.
