Nickel 30 vs. 7003 Aluminum

Nickel 30 belongs to the nickel alloys classification, while 7003 aluminum belongs to the aluminum 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 nickel 30 and the bottom bar is 7003 aluminum.
