EN-MC21120 Magnesium vs. Grade 3 Babbitt Metal
EN-MC21120 magnesium belongs to the magnesium alloys classification, while grade 3 Babbitt Metal 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 EN-MC21120 magnesium and the bottom bar is grade 3 Babbitt Metal.
