3 Aung et al.  showed that homogenization treatment and ageing treatment can improve the corrosion resistance of AZ91D magnesium alloy in 3.5% NaCl solution. In this paper, the influence of heat treatment on the microstructure and consequently on the
CORROSION RESISTANCE OF ALUMINIUM - Conways
It does corrode under some conditions. It is preferable to avoid corrosion through appropriate alloy choice and geometric design. Corrosion is a function of the operating environment, alloy and design. Understanding the mechanisms of corrosion enables more
Sacial Anode - Chemistry LibreTexts
Sacial Anodes are created from a metal alloy with a more negative electrochemical potential than the other metal it will be used to protect. The sacial anode will be consumed in place of the metal it is protecting, which is why it is referred to as a "sacial" anode.

What Stops Existing Salt Corrosion on Aluminum? | Hunker
All metals will corrode in the presence of salts. Though aluminum does not exhibit rusting like steel does, it will develop a chalky film and pitting in the metal surface when exposed to salt for long periods. A neutral soap and water wash will help remove the oxidized
The point of this alloy is that the other ingredients in the mix (mainly magnesium) is less noble than the aluminum and won’t corrode the base metal. An aluminum alloy that features copper, for instance, should never be used in saltwater – baaaad.
Scientists have long known that aluminum oxide does not corrode rapidly in water, but they have been unable to fully explain why. Now, for the first time, researchers have shown that liquid H

2011/6/3· The problem with Magnesium is that if it ignites, it is impossible to put out. There was a very bad accident in a race [Sebring, I think] involving a Mercedes Gullwing, which used a lot of Magnesium crashed & caught fire in the stands. The use of Magnesium in cars
Table of Corrosive Chemicals - Nidec Motors
Unpolluted rain water does not corrode aluminum. Fresh and salt waters in the pH range 4.5 - 8.5 cause only negligible attack of aluminum even at the boiling point, but certain of these waters cause pitting because they contain traces of heavy metal salts.
Why a magnesium case? : Surface
Magnesium is significantly lighter than aluminium (1700 vs 2700 kgm-3) which is a huge advantage. Corrosion-wise aluminium is substantially better, but you shouldn''t see any issues in a consumer product. With regards to the manufacturing, I''m not well versed in
