AlMgMn

These aluminum alloys are designed to offer high tensile strength and excellent corrosion resistance, making them ideal for applications in maritime, railway, and automotive fields, as well as in the construction of cryogenic tanks and pressure vessels. The main use of this alloy is in marine and structural applications where high strength levels, significant fracture toughness to withstand impacts, and solid resistance to corrosive elements are required. However, this alloy is not recommended for applications exposed to high temperatures, due to its susceptibility to stress corrosion cracking. It is also emphasized that the alloy is not subject to heat treatment.

Consumables for welding of Al-Mg, Al-Mg-Mn alloys up to 5% Mg.

Face-centered cubic lattice.

The alloy is not recommended for elevated temperature applications (> 65 °C) due to its susceptibility to stress corrosion cracking. The alloy is not-heat treatable.
