In many manufacturing industries, light weight components are produced using aluminum composite materials.But they lack good machinability and possess poor mechanical strength.

carbon nanotube (CNT) reinforced aluminum alloy 6061 (Al6061) composite was synthesized by stir casting process. Mechanical alloying was used to stir casting the CNTs in the matrix phase. The effects of the processing temperature (6000C, 6200C, and 6400C) on the microstructure, hardness, fracture surface and composition of the Al6061–MWCNT composite were investigated. Stir casting was used to 1 wt% MWCNT in aluminum (Al6061). Despite the success of stir casting for CNTs in Al 6061 material, Carbon nanotubes are the ultimate carbon fibers because of their high Young‘s modulus of ≈ 1 TPa which is very useful for load transfer in nanocomposites
