Abstract:
    This invention relates to a composite material of alumina dispersion copper and chrome-copper alloy, its manufacturing method and application, in which, the composite material is composed of alumina dispersion copper at the core and chrome-copper alloy surrounding the core, the volume percentage of the copper is 10-70% and that of the alloy is 30-90%. The manufacturing method includes: shaping them up by a thermal extruding machine, in which, when squeezing, a glass lubricated composite material blank and an extruding drum are used to meet the section ratio of them after extruding, and conductive nozzles and electrode caps used in welding machine are produced at low price, high accuracy and high material rate due to the high temperature strength and high conductivity of the material, dispersion copper used at part of the electric contact points of the core and chrome-copper as the blank outside.
