Experimental data show that aluminium doped RCo_5 systems crystallize in CaCu_5-type structure for most of the rare-earth elements (R). Al impurities randomly occupy one of the two possible positions (2c and 3g) and there is a critical concentration of Al, x_c=2.0, for RCo_{5-x}Al_x when the Co sublattice becomes nonmagnetic. The ab initio self-consistent calculations show strong dependence of magnetic properties of GdCo_{5-x}Al_x on concentration of Al and position of the impurities in the unit cell, furthermore to fulfil experimental observation of existence of critical concentration, x_c=2.0, the Al impurities should prefer 3g positions otherwise the magnetic moments on Co atoms do not vanish.
