C15715 is one of the few grades of dispersion-strengthened copper with lower alumina content. It features an entirely pure copper matrix with small but numerous Al2O3 particles, serving as an obstacle to the motion of dislocation. The Al2O3 distribution also has thermal stability and thus induces copper recrystallization obstruction. This means that a considerable amount of softening will not happen even after prolonged heating to high temperatures. This grade also has higher thermal and electrical conductivities and superior strength retention than most other copper alloys. They come in various forms, manufactured, such as rods and bars, strips and rerolled strips, wire, plates, and big rounds.

C15715 is ideal and is mainly designed to be in service where retaining the most electrical and thermal conductivities, in addition to working strength at high temperatures, is needed. It has perfectly working features when it comes to cold working and drawing to make fine wire, or rolling to manufacture sheets of small thicknesses is possible. Some of the applications of C15715 include, but are not limited to, multiterminal circuit package components, electrical components, relay blades, circuit breakers, switches, commutators in rotating devices, and high-power magnet windings.
