Abstract Results of static tensile testing of aluminium alloys 2024-T351 and 7075-T651 are presented with different levels of corrosion exposure in the laboratory environment. Specimens from two different rolling directions are tested (parallel and transverse rolling direction) after 7 and 30 days of corrosion exposure, respectively, using SCHENCK TREBEL Prüfmaschinen 4030 Ratingen, type RM100 testing machine. The obtained results indicate the change in the tensile properties depending on the time of corrosion exposure and moisture content. Keywords: aluminium alloy 2024-T351, aluminium alloy 7075-T651, corrosion, moisture, tension properties |
