Description of Dispersion Strengthened Copper Alloy C15715 (RWMA Class 21):
Cuberyllium C15715(RWMA Class 21) is a low alumina content grade of dispersion strengthened copper. It consists of a pure copper matrix containing finely dispersed sub-microscopic particles of Al O which act as a barrier to dislocation movement. The dispersed Al O is thermally stable so that it acts to retard recrystallization of the copper. Consequently, significant softening does not occur as the result of high temperature exposure. Along with superior strength retention, thermal and electrical conductivities are higher than conventional copper alloys.
Cuberyllium C15715(RWMA Class 21) is designated in UNS as C15715. This grade is available as rod and bar stock, strip and strip reroll, wire redraw, plates and large rounds. Most forms are available with or without an oxygen free copper cladding. Unless specified as “declad”, Cuberyllium is supplied with cladding.
