7010 Aluminum vs. Nickel 242

7010 aluminum belongs to the aluminum alloys classification, while nickel 242 belongs to the nickel alloys. 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 7010 aluminum and the bottom bar is nickel 242.
