C15715 DISPERSION STRENGTHENED COPPER

APPLICATIONS

C15715 is primarily designed for applications requiring the highest electrical and thermal conductivities along with good elevated temperature strength. It has excellent cold working characteristics, and can be drawn into fine wire or rolled into thin sheets. C15715 is recommended for hybrid circuit package components; vacuum tube, microwave tube, and X-ray tube components such as anodes, grids, cathodes, helixes, and heat sinks; electrical components such as circuit breakers, relay blades, and switches; rotating equipment components such as commutators, electric generator and motor components, and brush springs; and high power magnet windings.

DESCRIPTION

C15715 is a low alumina content grade of dispersion strengthened copper. It consists of a pure copper matrix containing finely dispersed sub-microscopic particles of Al2O3 which act as a barrier to dislocation movement. The dispersed Al2O3 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.  This grade is available as rod and bar stock, strip and strip reroll, wire redraw, plates and large rounds.
