Abstract
	In this paper, quantitative parameters of deformation of different metal materials have been analysed. The deformation was made by cold rolling on the laboratory two-high rolling stand. The samples of  low-carbon steel, aluminium, lead and copper, with different initial dimensions, were deformed. Reduction of the samples thiskness has been varied drom 15% to 90%, by step of 15%.
	Basic quantitative indicators of deformation, sucha s elongation, spreading and thickness reduction, have been calculated and the obtained values of indicators of deformation have been analysed. The influence of degree of deformation, geometrical parameters of samples and type of materials on the quantitative parameters of deformation has been analysed. It was shown taht the degree of deformation and type of material have the greatest influence on the quantitative parameters of deformation.
	The degree of deformation has the gretest influence on the parameters of the elongation – to 282%, less influence on the parameters of the thickness reduction – to 75,1% and the least influence of the parameters of  the spreading – to 7,6%.
	The values of the deformation parameters are different for different metal´s material. Aluminium has the highest values of elongation and copper – the lowest. For the indicators of spreading is opposite. Type of material especially influence on the spreading parameters. In dependence of the metal´s material, the values of the indicators of spreading differ to 195%.
	The geometrical parameters of the samples have the greatest influence on the defromation parameters. With the increase of the initial thickness and width of the samples, the values of all deformation indicators are increasing.
