UNS C14300 Cadmium Copper

C14300 copper is a lightly alloyed grade of copper, formulated for primary forming into wrought products.

The properties of C14300 copper include five 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 C14300 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.
