Silver and aluminum powders (82 mass % Ag and 18 mass % Al) were mixed and hot extruded at 673 K with extrusion ratio λ = 25. Performed X-ray diffraction analysis of as extruded rod revealed the development of Ag3Al and Ag2Al-type intermetallic phases. Structural observations and both chemical and diffraction analysis of structural components confirmed the growth of mentioned phases in the vicinity of elementary Al and Ag granules. No pores or voids were observed in the material. Mechanical properties of the composite, UTS = 490MPa, YS = 440 MPa, HV2 = 136, were relatively high if compared to commercial Ag and Cu products. Hot compression tests pointed to the good hot workability of the composite at deformation temperature range 473 K - 773 K.
