Solder Alloy 811 vs. R05255 Alloy

Both solder alloy 811 and R05255 alloy are otherwise unclassified metals. There are 17 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 811 and the bottom bar is R05255 alloy.
