Grade 702C Zirconium vs. 2218 Aluminum

Grade 702C zirconium belongs to the otherwise unclassified metals classification, while 2218 aluminum belongs to the aluminum alloys. There are 21 material properties with values for both materials. Properties with values for just one material (11, 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 grade 702C zirconium and the bottom bar is 2218 aluminum.
