Solder Alloy 131 vs. MDF

Solder alloy 131 and MDF belong to fundamentally different material chemistries. Solder alloy 131 is a metal, while MDF is a polymeric material. Therefore, their performance will be even more dissimilar than would be suggested by the difference in properties. There are 15 material properties with values for both materials. Properties with values for just one material (10, 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 131 and the bottom bar is MDF.
