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.

Jimmy:

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.

There are many forms of corrosion. Go 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
