UNS C19100 Nickel-Tellurium Copper
C19100 copper is a lightly alloyed grade of copper, formulated for primary forming into wrought products. It can have a moderately high ductility among the wrought coppers in the database.
The properties of C19100 copper include four 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 C19100 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.
