The paper will present results of mechanical tests and grain structure investigation of aluminium wires obtained by plastic consolidation of aluminium powders produced by atomisation from liquid state. The powders production by this method could be potentially adopted to obtain ultra fine/nano structured materials by rapid solidification and/or subsequent milling. Conversion of material from powder to bulk state with retaining of powders fine structure and minimizing of porosity are problems resolving of which is crucial for such technological rout of nanometals production. An influence of condition of plastic consolidation by hot extrusion on mechanical properties of consolidated products is a main target of presented investigation. The standard mechanical properties of extrusion products have been determined and grain structure has been inspected. The results have been compared to extrusion products of conventional bulk aluminium. It has been stated substantial increase of properties and refining of grain structure in materials consolidated from powders and negligible porosity of consolidated products.
