Corrosion resistance of aluminum and magnesium alloys : understanding, performance, and testing / Edward Ghali. p. cm. Includes index. ISBN 978-0-471-71576-4 (cloth) 1.
The corrosion resistance of aluminum is due to its tendency to form a compact oxide layer over the surface. The oxide formed offers a high resistance to corrosion. The
Alloying pure aluminum with different metals modifies the mechanical properties and changes other properties of alloys, such as density, formability,

Aluminum as an engineering material ranks in tonnage use only behind iron and steel, and its growth in production has been continually increasing year by year. The global tonnage shipped in 2007 was 60. Mt, of which 37. Mt was provided by primary production and 23. Mt by recycled scrap. 3 Aluminum is unique in its high level of recyclability
Alloys in the 5000-seriesbecome susceptible to intergranular corrosion if the Mg content exceeds 4.5 %. The 6000-series may also become susceptible to intergranular corrosion if the Si/Mg ratio exceeds thestoichiometric ratio for the intermetallic compound Mg2Si, especially if Cu is also present,even if in small
Aluminum (more 99,9 % Al) Ultrapure aluminum (more 99,9 % Al) shows the highest corrosion resistance. It dramatically decreases with increasing impurity content, especially copper and iron. Aluminum alloys of Al-Mn Al-Mn alloys have very good corrosion resistance and are used outdoors without any protection. Aluminum alloys
