aluminum alloy

Dear Sirs,
Can somebody tell me which aluminum alloy will corrode higher in 3% NaCl solution: EN AW-5005 (with 0.8% Mg) or EN AW-5052 (with 2.6% Mg). I would
like to get complete explanation. Can you also tell me where I can find explanations in theory about my question (some easily accessible book, scientific papers, or free web sites)?
Thanks in advance for your answers.

You can find an answer in the Metals Handbook, 9th Edition, Volume 13, Corrosion, ASM International, Metals Park, Ohio, 1987. See page 586. Go find it in your friendly local engineering library.
If you prefer fooling around online, then go look it up in the Alubook. http://www.alu-info.dk/Html/alulib/modul/A00148.htm
There are many forms of corrosion. Go to: http://kentengineering.com/KE_Publications.pdf to see the more recent general section on this topic from ASM Handbook Volume 11, Failure Analysis and Prevention, ASM International, 2002
The best online textbook on aluminum alloys (and including their corrosion behavior) is Talat http://www.eaa.net/eaa/education/TALAT/5000/5100.htm Look at sections 5101, 5102 and particularly 5103 Corrosion control of aluminium - forms of corrosion and prevention http://www.eaa.net/eaa/education/TALAT/lectures/5103.pdf
