ISO-WD32250 Magnesium vs. AISI 431 Stainless Steel

ISO-WD32250 magnesium belongs to the magnesium alloys classification, while AISI 431 stainless steel belongs to the iron alloys. There are 30 material properties with values for both materials. Properties with values for just one material (4, 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 ISO-WD32250 magnesium and the bottom bar is AISI 431 stainless steel.
