The recent scenario is all about enhancing the properties for different applications according to the acquired properties. In this work, the aluminium 6082 material is chosen as it has more Si percentage which might lead to alteration in properties. In the present work, aluminium 6082 material is solution treated first to a temperature of 450 °C, furnace cooled, air cooled, water quenched, castor oil quenched, sunflower oil quenched and then age hardened to 200 °C temperature for 2, 4 and 6 h with air cooling. Microstructure and hardness tests are conducted and are found that the untreated Al-6082 alloy recorded lower RHN than the heat-treated Al-6082 alloy in the case of air cooling, whereas in the case of furnace cooling, an untreated Al-6082 alloy recorded higher value than heat-treated Al-6082 alloy.
