UNS C11600 (CW013A) Silver-Bearing Tough Pitch Copper

C11600 copper is a lightly alloyed grade of copper, formulated for primary forming into wrought products. CW013A is the EN numeric designation for this material. C11600 is the UNS number. Additionally, the SAE designation is CA116.

It has a moderately high base cost among the wrought coppers in the database.

The properties of C11600 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 C11600 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 C11600 copper is notable for including silver (Ag). Silver is used to increase recrystallization temperature in copper alloys. This permits operation at higher temperatures without permanent loss of mechanical properties.

Copper (Cu) 99.78 to 99.915
Silver (Ag) 0.085 to 0.12
Residuals 0 to 0.1
