This correspondence, a three-dimensional radiative magnetohydrodynamic flow of hybrid nanofluid across an exponentially stretching surface is discussed. In this study we contemplate aluminium alloys of 7072 and 7072 + 7075 T6 type with transformer oil base liquid. AA7070 is composition of Zinc and aluminium in the ratio of 98 & 1 with supplementary metals Copper, Magnesium, Zinc and Aluminium in the proportion of, ~ 1, ~3, ~ 6, and ~ 90 correspondingly. AA 7075 is a composite of 90% Al, 5.5% Zn, 2.6% Mg, 0.24% Cr and 1.5% Cu. The density of these alloys’ mixture is 3.81 gm/cm3. It is one of the strongest aluminium alloys having reinforce process (heat treatment up to 300-500o C) to reconfigure any metal’s crystal structure to provide the mechanical deformation at low density than others metal alloys. These alloys mixture found some applications in Missile parts making, Aerospace system, Défense, Aircraft designing and fittings, Steel worm gears and in many others discipline. These alloy mixtures are treated in conventional fluid to enhance the heat transfer characteristics of nanofluid. Flow is induced by Cattaneo-Christov heat mass flux model perception. The solutions of reduced dimensionless nonlinear ordinary differential equations are handled through Mathematica built-in ND Solve scheme. Significant role of several physical parameters govern by the equation of motions are discussed through plots. Comparisons with the previously published article also validate the efficiency of the technique as well. Results, shows that the heat transfer rate of the AA7072/ AA7075 hybrid nanofluid is remarkably enormous as compared with the usual nanofluid.
