UNS C10700 (CW019A) Oxygen-Free Silver-Bearing Copper

C10700 copper is a lightly alloyed grade of copper, formulated for primary forming into wrought products. CW019A is the EN numeric designation for this material. C10700 is the UNS number. Additionally, the EN chemical designation is CuAg0,10 OF.

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

The properties of C10700 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 C10700 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 C10700 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.
