Conclusions 1. The optimum temperature for rolling aluminum granules may be taken to be 400–450°C. 2. The parameters of the first reduction of granules affect the mechanical properties of the end product: increasing the reduction of granules improves the mechanical and physical properties of the material. 3. The highest mechanical and physical properties are exhibited by material at 40–50% reduction, subjected to additional working after annealing. 4. Oxide inclusions distributed throughout the matrix as a result of the disintegration of the granule boundaries during deformation have no significant effect on the mechanical properties of the material. 5. The addition of 2% of aluminum dust of high oxide content to the granules strengthens the material without significantly lowering its ductility.
