1230A Aluminum vs. C86500 Bronze

1230A aluminum belongs to the aluminum alloys classification, while C86500 bronze belongs to the copper 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 1230A aluminum and the bottom bar is C86500 bronze.
