As-Cast Type 2 Pewter
As-cast Type 2 pewter is Type 2 pewter in the as-fabricated (no temper or treatment) condition. It has the highest strength compared to the other variants of Type 2 pewter. The graph bars on the material properties cards below compare as-cast 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.
