Light Drawn (H55) C12000 Copper
H55 C12000 copper is C12000 copper in the H55 (light drawn) temper. The graph bars on the material properties cards below compare H55 C12000 copper to: wrought 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.
