TM05 Mill Hardened C17200 Copper
TM05 C17200 copper is C17200 copper in the TM05 (mill hardened to spring-hard) temper. The graph bars on the material properties cards below compare TM05 C17200 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.
