# Heat Treated (HT) C82200 Copper

HT C82200 copper is C82200 copper in the heat treated (HT) condition. The graph bars on the material properties cards below compare HT 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.
