Light Drawn (H55) C10800 Copper
H55 C10800 copper is C10800 copper in the H55 (light drawn) temper. The graph bars on the material properties cards below compare H55 C10800 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.
