Solution Annealed ASTM B563 vs. Solution-treated Grade 21 Titanium
Solution annealed ASTM B563 belongs to the otherwise unclassified metals classification, while solution-treated grade 21 titanium belongs to the titanium alloys. There are 17 material properties with values for both materials. Properties with values for just one material (15, 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 solution annealed ASTM B563 and the bottom bar is solution-treated grade 21 titanium.
