TM02 Mill Hardened C18600 Copper

TM02 C18600 copper is C18600 copper in the TM02 (mill hardened to half-hard) temper. The graph bars on the material properties cards below compare TM02 C18600 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.
