UNS C10100 (CW009A) Oxygen-Free Electronic Copper

C10100 copper is a lightly alloyed grade of copper, formulated for primary forming into wrought products. CW009A is the EN numeric designation for this material. C10100 is the UNS number. Additionally, the SAE designation is CA101. And the AFNOR (French) designation is Cu-c2.

The properties of C10100 copper include eleven 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 C10100 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.

Alloy Composition

Among wrought copper alloys, the composition of C10100 copper is notable for including phosphorus (P). Phosphorus is used as an alloy deoxidizer, and to reduce vulnerability to dezincification.

Copper (Cu) 99.99 to 100
Lead (Pb) 0 to 0.0010
Oxygen (O) 0 to 0.00050
Phosphorus (P) 0 to 0.00030
Zinc (Zn) 0 to 0.00010
