UNS C19200 Iron-Bearing Copper

C19200 copper is a lightly alloyed grade of copper, formulated for primary forming into wrought products. C19200 is the UNS number for this material. Additionally, the EN chemical designation is CuFe1P.

The properties of C19200 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 C19200 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 C19200 copper is notable for including phosphorus (P). Phosphorus is used as an alloy deoxidizer, and to reduce vulnerability to dezincification.

Copper (Cu)Cu 98.5 to 99.19
Iron (Fe)Fe 0.8 to 1.2
Zinc (Zn)Zn 0 to 0.2
