Excellent specific resistance due to low density and high mechanical properties
Thermally stable, even if subject to cycles
Less corrosion resistant than other aluminium alloys

Thanks to the zinc alloy, this aluminium is distinguished by its high mechanical properties that are similar to those of some steels. Its impact resistance and ductility are excellent, as well as its thermal stability with varying temperatures. Its resistance to fatigue and cyclic loads, which is fundamental in the aeronautical sector, is also of equal interest.
