Cold Rolled Type 2 Pewter

Cold rolled Type 2 pewter is Type 2 pewter in the cold worked (strain hardened) condition. It has the lowest strength compared to the other variants of Type 2 pewter. The graph bars on the material properties cards below compare cold rolled Type 2 pewter to: tin alloys (top), all alloys in the same category (middle), and the entire database (bottom). A full bar means this is the highest value in the relevant set. A half-full bar means it's 50% of the highest, and so on.
