The processing of AA1050 with a tapered square pin at a tool rotation speed of 1200 rpm yielded the highest strain of 0.345 at ultimate tensile strength compared with 0.054 in as-received material. The identified processing conditions produced an ultimate tensile strength of 89.23 MPa with a toughness of 34.451 × 106 J/m3 and a lower corrosion rate with I<inf>corr</inf> of 0.324 × 10?6 A/cm2. Further, processing with a simple tapered circular pin resulted in maximum ultimate tensile strength of 102 MPa with a toughness of 33.990 × 106 J/m3. However, it came at the expense of least resistance to corrosion with I<inf>corr</inf> of 4.813 × 10?6 A/cm2. Consequently, the addition of zinc oxide during friction stirring showed a remarkable improvement in corrosion resistance with I<inf>corr</inf> of 0.094 × 10?6 A/cm2. Future studies are planned on these lines. © 2020, The Minerals, Metals & Materials Society.Corrosion rateCorrosive effectsFrictionFriction stir weldingII-VI semiconductorsTensile strengthZinc oxideCorrosion behaviorFriction stir processingFriction stirringProcessing conditionRolled sheetsTool rotationsUltimate tensile strengthCorrosion resistance
