WE54A Magnesium vs. R04295 Alloy

WE54A magnesium belongs to the magnesium alloys classification, while R04295 alloy belongs to the otherwise unclassified metals. There are 18 material properties with values for both materials. Properties with values for just one material (14, in this case) are not shown. Please note that the two materials have significantly dissimilar densities. This means that additional care is required when interpreting the data, because some material properties are based on units of mass, while others are based on units of area or volume.

For each property being compared, the top bar is WE54A magnesium and the bottom bar is R04295 alloy.
