Calculation results regarding the concentration dependence of the electrical transfer parameters of resistivity, mean free path and Fermi energy for high-entropy alloys HEA (number of components from 4 to 6) in the form of film or bulk alloys are presented. Calculations were made assuming the additivity of parameters, which in the case of resistivity is confirmed experimentally. Based on the obtained results and analysis of the Fermi surface form for HEA, a qualitative conclusion is made regarding the fact that studied in the work HEA should not be classified as new substances, since they are one of the types of metallic solid solutions with electronic parameters close in magnitude to metals.
