The current study deals with the main features of heath treated aluminium alloy EN-AW 1050A H24 to be used for structural applications. This is an almost pure aluminium whose employment is innovative in the civil engineering field and that, for this reason, needs to be carefully investigated in relation to its performance. On this prospective the main results of a wide experimental campaign, carried out on specimens subjected to static or dynamic loadings, as well as to monotonic or cyclic strains, are shown. In addition, some remarks about the residual stresses induced by welding processes are given. Finally, analytical or numerical models obtained by the above tests are provided.
