Aluminium Alloy 6061 has become a widely used material because of its super-spec properties including impressive mechanical features as well as corrosion resistance. Its main element is aluminum in addition to magnesium and silicon as the principal third party additions. This alloy has a nominal chemical composition with 97.9% aluminum, 1% magnesium and 0.6% silicon, thus its properties are the best in terms of strength, machinability and weldability. Today it is a go-to material for structures because of its high tensile strength and good shaping abilities while still relevant for industrial uses. Its strength can range from tempered grade 5 with good corrosion resistance to tempered grade 9, the highest grade, that has both high strength and corrosion resistance. Form, like, sheet, plate, bar, or extrusion, alloy 6061 is available in almost all conceivable wide range and is used commonly among the majority of industries due to its properties.
Aluminium Alloy 6061 is one of the materials which possess great strength-to-weight ratio, consequently, this makes it perfect not only for aerospace, automotive and construction industries usages, but also for appliances. The main chemical constituents of bauxite range from 95.85- 98.56% aluminum, 0.40- 0.80% silicon, 0.15-0.40% copper, 0.8-1.2% magnesium, 0.04-0.35% chromium, 0.15 maximum z The grade 61 alloys have excellent characteristics such as good resistance to corrosion, welding ability and ease of machine work. It has been found mainly in architecture, machine parts and consumer items with the idea of giving an edge to industry.
