UNS C11000 (CW004A) Electrolytic Tough Pitch Copper

C11000 copper is a lightly alloyed grade of copper, formulated for primary forming into wrought products. CW004A is the EN numeric designation for this material. C11000 is the UNS number. Additionally, the SAE designation is CA110. The British Standard (BS) designation is C101. And the AFNOR (French) designation is Cu-a1.

The properties of C11000 copper include ten common variations. This page shows summary ranges across all of them. For more specific values, follow the links immediately below. The graph bars on the material properties cards further below compare C11000 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.
