Abstract
A 3-D magnetohydrodynamic flow of hybrid nanofluid across a stretched plane of non-uniform thickness with slip effects is studied. We pondered aluminum alloys of AA7072 and AA7072 + AA7075 in methanol liquid. The aluminum alloys amalgamated in this study are uniquely manufactured materials, possessing enhanced heat transfer features. AA7072 alloy is a composite mixture of Aluminum & Zinc in the ratio 98 & 1 respectively with added metals Silicon, ferrous and Copper. Equally, AA7075 is a mixture of Aluminum, Zinc, Magnesium, and Copper in the ratio of ~90, ~6, ~3 and ~1 respectively with added metals Silicon ferrous and Magnesium. Numerical solutions are attained using R-K based shooting scheme. Role of physical factors on the flow phenomenon are analyzed and reflected by plots and numerical interpretations. Results ascertain that heat transfer rate of the hybrid nanoliquid is considerably large as matched by the nanofluid. The impact of Lorentz force is less on hybrid nanofluid when equated with nanofluid. Also, the wall thickness parameter tends to improve the Nusselt number of both the solutions.

Summary
Advanced electronic gadgets frequently encounter challenges because of heat control from enhanced thermal rise or reduction of available space for the thermal emission. They revealed that hike in thermal radiation results in the improvement of heat transfer performance of the liquid. The effect of aligned magnetic field on the slippery flow of nanofluid was numerically studied by Acharya et al.[34]. Effect of internal heat source and radiation on 3-D flow of nanofluid past a shrinking sheet was theoretically studied by Sharma et al.[37].
