C54400 Bronze vs. ZK60A Magnesium

C54400 bronze belongs to the copper alloys classification, while ZK60A magnesium belongs to the magnesium alloys. There are 24 material properties with values for both materials. Properties with values for just one material (8, 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 C54400 bronze and the bottom bar is ZK60A magnesium.
