UNS C15900 Dispersion Strengthened Copper
C15900 copper is a lightly alloyed grade of copper, formulated for primary forming into wrought products. Cited properties are appropriate for the M30 (as hot extruded) condition.
It has a fairly high tensile strength among wrought coppers. In addition, it has a moderately high embodied energy and a moderately low electrical conductivity.
The graph bars on the material properties cards below compare C15900 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.
