The work deals with solderabilty of high-purity aluminium with the lead-free tin solders. Soldering was performed in the air with and without application of flux and with mechanical removal of surface oxides. Wettability measurements have shown that all lead-free solders wetted aluminium surface with wetting angle below 42°. The shear strength of experimental joints attained the values from 25 to 48 MPa. The study of boundary zones of fabricated joints was performed by use of EDX analysis.
