Solution Annealed ASTM B540 vs. Solution Annealed ASTM B563

Both solution annealed ASTM B540 and solution annealed ASTM B563 are otherwise unclassified metals. Both are furnished in the solution annealed (AT) condition. They have 80% of their average alloy composition in common. There are 20 material properties with values for both materials. Properties with values for just one material (4, in this case) are not shown.

For each property being compared, the top bar is solution annealed ASTM B540 and the bottom bar is solution annealed ASTM B563.
