Aluminium is the mainly abundant metal in the earth crust and be the second largest used metal and largest nonferrous in the world. Aluminium alloys with a huge range of mechanical properties are used in various aerospace automotive applications due to their lower weight, lower density, and excellent corrosion resistance, Al Alloys are extensively used in the aerospace industry.
Aluminium 6061 alloy is one of the most broadly used medium strength heat treatable all alloys in the aerospace and automobile industries. It exhibits high-quality strength-ductility and toughness. The solid solution strengthening and precipitation hardening treatment are imparted to this alloy to enhance its strength. Magnesium and silicon are the main alloying elements in this alloy, form precipitate through T6 treatment, which increases the strength of this alloy.
