As Cast C82200 Copper
As-cast C82200 copper is C82200 copper in the as-fabricated (no temper or treatment) condition. The graph bars on the material properties cards below compare as-cast C82200 copper to: cast coppers (top), all copper alloys (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.
