ASTM A387 Grade 12 Class 1 vs. Rolled And Annealed Type 2 Pewter

ASTM A387 grade 12 class 1 belongs to the iron alloys classification, while rolled and annealed Type 2 pewter belongs to the otherwise unclassified metals. There are 20 material properties with values for both materials. Properties with values for just one material (12, in this case) are not shown.

For each property being compared, the top bar is ASTM A387 grade 12 class 1 and the bottom bar is rolled and annealed Type 2 pewter.
