Abstract: A composite formulation and composite product are disclosed. The composite formulation includes a polymer matrix having metal particles, the metal particles including dendritic particles and tin-containing particles. The metal particles are blended within the polymer matrix at a temperature greater than the melt temperature of the polymer matrix. The tin containing particles are at a concentration in the composite formulation of, by volume, between 10% and 36%, and the dendritic particles are at a concentration in the composite formulation of, by volume, between 16% and 40%. The temperature at which the metal particles are blended generates metal-metal diffusion of the metal particles, producing intermetallic phases, the temperature being at least the intermetallic annealing temperature of the metal particles.
