In the paper the theoretical sintering criterion was applied to check if sintering conditions of bearing aluminium matrix composites manufactured by recycling of communited aluminium and CuA18 aluminium bronze chips, as reinforcing phase, determined experimentally were proper chosen. The criterion bases on the assumption that by conformability of plastic work of composites in metal working processes with critical values of the work needed for good junction of the particles determined in other simple test, the proper conditions of bonding process of particles can be achieved. The composites were manufactured directly, without metallurgical process. The method of recycling contains: cleaning and communition of chips, premolding, hot extrusion and heat treatment during which the diffusion of copper and aluminium between matrix and reinforcing phase takes place and leads to create the hard intermetallic phases in soft matrix, the structure typical for bearing materials.
