The feasibility of recycling machining grindings of aluminum alloys by semisolid processhas been investigated. Machining grindings of A2011 aluminum alloy produced experimentally bylathe machining were used. The material is put into a metal mold and compressed up to 90 % of thetrue density at room temperature. The metal mold with the compressed machining grindings isheated up to a specified temperature. Afterwards, the metal mold is set into the extrusion container,and extrusion in hot and semisolid range was carried out. In this experimental study, extrusion load,internal structure of the product and mechanical properties (tensile strength, elongation, hardness) ofthe product are assessed. It was proven that semisolid extrusion is about 40% less extrusion loadcompared with that of hot extrusion, the shape of the machining grindings remained in the hotextrusion and the semisolid extrusion products extrusion ratios higher than 10 have excellentelongation property, which is comparable to the commercialized product
