520.0 Aluminum vs. AM100A Magnesium
520.0 aluminum belongs to the aluminum alloys classification, while AM100A magnesium belongs to the magnesium alloys. They have a modest 20% of their average alloy composition in common, which, by itself, doesn't mean much. There are 31 material properties with values for both materials. Properties with values for just one material (1, in this case) are not shown.
For each property being compared, the top bar is 520.0 aluminum and the bottom bar is AM100A magnesium.
