2017A-T4 -- classic aircraft rivet and general engineering aluminium alloy. Rm 390-440 MPa, naturally aged. Traditional Duralumin successor for solid rivets and general machined parts.
EN AW-2017A (AlCu4MgSi(A)) per EN 573-3. Direct descendant of the original 1906 Duralumin. T4 natural aging gives Rm 390-440 MPa with good machinability. Standard for aircraft solid rivets, aerospace machined fittings and high-strength engineering components.
