The experimental researches made to settle the behaviour at cold plastic deformation of Al-Li alloys used in aeronautical constructions was realized on anneal samples through upsetting, rolling, drawing and torsion methods.The aim of this paper is to determined the behaviour at cold plastic deformation and the maximum possible degree of deformation, until don't appear cracks, through these four methods presented above for some Al-Li base alloys.By examination of the results obtained through these methods, it was determined the maximum possible degree of deformation until don't appear cracks and the equations which describe the behaviour of the tested alloy to cold plastic deformation.
