T1 - Long term corrosion behavior of clad aluminium materials under different atmospheric conditions N2 - Aluminum materials roll-plated on both sides are combinations of metals, which consist of clad layers on a core. To document the long term behavior of roof profiles of Alclad 3004 after long term exposure of about 40 years, evaluations were made at three locations in Germany with different climatic conditions. Locations with typical rural-urban, coastal-urban, and industrial climates were selected. The corrosion progress as a function of time and climatic type could be characterized by cross-sections of roof specimens. To interpret the protective mechanism of the clad layer, the corrosion behavior of Alclad 6025 was characterized by electrochemical investigations. The results show that the passive clad material easily undergoes pitting in media containing specific amounts of chlorides. In case of contact of both cladding and core with an electrolyte the core alloy was protected because of the pitting corrosion of the cladding. This guarantees long-time corrosion protection of constructions like facades or roofs under different atmospheric conditions.
