1070A Aluminum vs. Solder Alloy 115

1070A aluminum belongs to the aluminum alloys classification, while solder alloy 115 belongs to the otherwise unclassified metals. There are 25 material properties with values for both materials. Properties with values for just one material (6, 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 1070A aluminum and the bottom bar is solder alloy 115.
