UNS C15100 Zirconium Copper
C15100 copper is a lightly alloyed grade of copper, formulated for primary forming into wrought products. C15100 is the UNS number for this material. Additionally, the EN chemical designation is CuZr0,15.
The properties of C15100 copper include seven 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 C15100 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.
