ABSTRACT:
An electrically conductive composite material is formed by dispersing in a matrix metal the other metal which is not solid soluble with the matrix metal. The other metal is finely divided to an extent of not excessively lowering the conductivity and is mixed in the matrix metal in a particle amount with which respective particles keep a mutual distance effective to strengthen the composite material, whereby the material is sufficiently improved in the mechanical strength and wear resistance and remarkably reduced in the high temperature deformation. Such conductive composite material can be obtained through a melt atomization.
