An analysis of experimental data on the relationship between the density and thickness of strips rolled from iron, nickel, aluminum, titanium, and stainlesssteel powders in rolling mills with different roller diameters was performed. It was shown that the dependence of the density on the thickness of strips is determined by the method used for varying the strip thickness.

It was found that the density of strips heavily depends on the strip width. A method for calculating the density of rolled strips which takes into account all the geometric and physicomechanical parameters of the process and which yields results that are in good agreement with experimental data was proposed.
