C90500 Gun Metal vs. ZK60A Magnesium

C90500 gun metal belongs to the copper alloys classification, while ZK60A magnesium belongs to the magnesium alloys. There are 29 material properties with values for both materials. Properties with values for just one material (3, 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 C90500 gun metal and the bottom bar is ZK60A magnesium.
