Aluminum alloy 5754 (AlMg3) has a high welding and strength properties and also a good resistance to atmospheric and marine corrosion. The alloy is used in many industries such as automotive, railway, marine building, electricity, chemistry and forging. In this work, strength properties of aluminum alloy 5754 (AlMg3) after an acid salt spray (CASS) test and neutral salt spray (NSS) test have been investigated. It can be concluded, that after 240 hours of duration of (CASS) test of Al alloy 5754 (AlMg3), the plastic elongation A50 showed the greatest decreasing (up to 50%), whereas performed (NSS) test during 1512 hours (9 weeks) of the same Al alloy does not show decreasing of any strength properties. The mechanical properties of tested alloy after (NSS) test were on the same as initial level. On the basis of obtained results it can be concluded, that acetic acid salt spray (CASS) test may cause significant decreasing of strength properties which can cause too early destruction of elements used in industry.
