A380.0 Aluminum vs. C70400 Copper-nickel

A380.0 aluminum belongs to the aluminum alloys classification, while C70400 copper-nickel belongs to the copper alloys. There are 26 material properties with values for both materials. Properties with values for just one material (6, 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 A380.0 aluminum and the bottom bar is C70400 copper-nickel.
