2095 Aluminum vs. CC760S Brass

2095 aluminum belongs to the aluminum alloys classification, while CC760S brass belongs to the copper alloys. There are 28 material properties with values for both materials. Properties with values for just one material (4, 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 2095 aluminum and the bottom bar is CC760S brass.
