Here we present a new approximation for calculation of density of states of multicomponent metallic alloys using Lloyd formula. We consider the average square of Tmatrix as the pair replication of scattering system. The analytical expressions are probed on Ti_{x}Mn_{1x} and Al_{x}Ni_{1x} binary alloys. The results are in good agreement with the predicted behavior of density of states for such systems.
