Abstract: Aluminum alloy 6061 is one of the most extensively used of the 6000 series aluminum alloys. Aluminum in its purest form is too soft and reactive to be of structural use. However, its alloys such as 6061-T6 alloy, makes it structurally stronger. In the present investigation typical commercial grade Al 6061 alloy obtained from leading professional environments would be the test materials for investigations. The Al 6061 alloy has been subjected to solutionizing treatment at a temperature of 540?C for 2 hours followed by quenching in water. The quenched specimens are subjected to artificial ageing. Tensile test, and hardness tests have been conducted on the specimens subjected to heat treatment. It has been observed under identical heat treatment conditions adopted, Al 6061-subjected to heat treatment under T6 conditions exhibited a significant improvement in hardness when compared with Al 6061 before heat treatment.
