3102 Aluminum vs. C19800 Copper

3102 aluminum belongs to the aluminum alloys classification, while C19800 copper belongs to the copper alloys. There are 29 material properties with values for both materials. Properties with values for just one material (1, 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 3102 aluminum and the bottom bar is C19800 copper.
