UNS C11100 Electrolytic Tough Pitch Copper
C11100 copper is a lightly alloyed grade of copper, formulated for primary forming into wrought products. Cited properties are appropriate for the H04 (full hard) temper. It has a fairly low ductility and a moderately high tensile strength among wrought coppers.
The graph bars on the material properties cards below compare C11100 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.
