Solder Alloy 502 vs. 5252 Aluminum

Solder alloy 502 belongs to the otherwise unclassified metals classification, while 5252 aluminum belongs to the aluminum alloys. There are 22 material properties with values for both materials. Properties with values for just one material (9, 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 solder alloy 502 and the bottom bar is 5252 aluminum.
