Solder Alloy 704 vs. R05252 Alloy

Both solder alloy 704 and R05252 alloy are otherwise unclassified metals. There are 14 material properties with values for both materials. Properties with values for just one material (13, 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 704 and the bottom bar is R05252 alloy.
