Annealed ASTM B780 Alloy vs. Rolled And Annealed Type 2 Pewter
Both annealed ASTM B780 alloy and rolled and annealed Type 2 pewter are otherwise unclassified metals. Both are furnished in the annealed condition. There are 14 material properties with values for both materials. Properties with values for just one material (10, in this case) are not shown.
For each property being compared, the top bar is annealed ASTM B780 alloy and the bottom bar is rolled and annealed Type 2 pewter.
