The article gives the results of experiments on forming of cast secondary aluminum alloys using the new deformation method - screw extrusion. It is shown that worm screw extrusion with back pressure gives rise to good processing of the cast structure and fragmentation of brittle intergranular skeleton in casting blocks of secondary aluminum. As a result, ductility of alloy increases and a possibility appears to use traditional methods of metal forming for the purpose of obtaining necessary form.
