CC495K Bronze vs. ISO-WD21150 Magnesium

CC495K bronze belongs to the copper alloys classification, while ISO-WD21150 magnesium belongs to the magnesium alloys. There are 28 material properties with values for both materials. Properties with values for just one material (2, 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 CC495K bronze and the bottom bar is ISO-WD21150 magnesium.
