The invention discloses an alloy conductive plastic, which belongs to the technical field of plastics. The alloy conductive plastic comprises a substrate and a conductive material, wherein the substrate is a nylon material of which the relative viscosity is 1.5-1.7; and the conductive material is alloy powder of Cu, Fe, Ni and Ag of 100-150 meshes, and is blended, pelletized and molded. The volume ratio of the alloy powder of Cu, Fe, Ni and Ag is 1:1:1:1, and the mass ratio of the nylon material to the alloy powder is 10:3-10:6. The conductive plastic produced in the invention has the advantages of high volume resistivity, low specific weight, high tensile strength, current conductivity, heat conductivity, wear resistance, self-lubrication and the like, and can be used for manufacturing various plastic products having the characteristics of current conductivity, heat conductivity, electromagnetic shielding, static resistance and the like.
