ASTM A225 Steel vs. Type 2 Pewter
ASTM A225 steel belongs to the iron alloys classification, while 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 (11, in this case) are not shown.
For each property being compared, the top bar is ASTM A225 steel and the bottom bar is Type 2 pewter.
