Grade 25 Titanium vs. Solder Alloy 112

Grade 25 titanium belongs to the titanium alloys classification, while solder alloy 112 belongs to the otherwise unclassified metals. There are 23 material properties with values for both materials. Properties with values for just one material (7, 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 grade 25 titanium and the bottom bar is solder alloy 112.
