Type 2 Pewter vs. Grade TDC Steel

Type 2 pewter belongs to the otherwise unclassified metals classification, while grade TDC steel belongs to the iron alloys. There are 20 material properties with values for both materials. Properties with values for just one material (6, in this case) are not shown.

For each property being compared, the top bar is Type 2 pewter and the bottom bar is grade TDC steel.
