Hi Vijaydeshin

I would expect them to be generally similar for protecting iron and steel against corrosion. Al5Mg is a little more "active" (sacrificial) than pure aluminium and sometimes specified for use in marine environments by a few companies. Not really sure of the pros and cons though.

Sorry for wrong button.
The Norwegians, who are really fighting with environmental corrosion, has considered that Al5Mg has performed best in their off-shore applications.
