Aluminium

·        Silver-white metal.

·        Firstly, found in 1824.

·        It is non-magnetic, ductile (ability to be drawn into a thin wire) and soft, conductive.

·        It is malleable (ability to be pressed into shape without breaking)

·        It has a great ability to resist the corrosion.

·        Chief ore of Aluminium is Bauxite.

·        It is three times lighter than iron.

·        It does not magnetize

·        It is easy in the processing and 100% recyclable.

·        It never catches the fire.

·        It is used as an alloy.

·        Aluminium has better thermal conductivity hence it is used for car radiators and A.C units.

·        It is cheaper than the stainless steel.

·        Melting Point: -660 degrees

·        Aluminium is manufactured in the two processes. The Bayer process of refining the bauxite ore to obtain the aluminium oxide and the Hall-Heroult process of smelting (extracting the metal from the ore by melting) the aluminium oxide to release pure aluminium.

·        Alumina, the intermediate substance that is produced by the Bayer process and that constitutes the raw material for the Hall-Heroult process, is also a useful final product.

·        It is a white, powdery substance with a consistency that ranges from that of talcum powder to that of granulated sugar. It can be used in a wide range of products such as laundry detergents, toothpaste, and fluorescent light bulbs.

·        Tensile strength of Aluminium increases as its temperature drops.

·        2kg of bauxite is required to produce 0.5kg of Aluminium.

·        First, you dig the bauxite from the ground, crush it up, dry it to leave just the aluminium oxide. Then you use an electrical technique called electrolysis (to split into aluminium and oxygen). Once it is done, the pure aluminium is casted into blocks known as ingots, which are used as a raw material for making the aluminium alloys.

·        Australia produces one third of world’s Bauxite.

·         Many cooking pots are made up of Aluminium.

·        Being a lightweight, Aluminium is used in architectural applications.

·        Ingots of Aluminium are about 16tons.

·        Used in transportation because of its strength and weight ex. Aeronautical applications and aircraft sealings and in bullet trains.

·        Non-magnetic the property makes it suitable to produce consumer goods as TV appliances, and electric appliances.

·        Due to lower density, Aluminium is used for long-distance power lines. Its ductile nature allows it to be merged easily with the wires. It's corrosion-resistant property is beneficial in the electrical industry.

·        Its non-toxic and odorless properties make it suitable for the packaging of food and pharmaceutical products and producing the pressure cooker and the cooking utensils.

·        Its sound absorbing nature makes it suitable to use as auto-bumpers.

·        Aluminium never produces any spark.

·        Average Aluminium content in the car will increase by 60% until 2026.

·        Current cost per kg in the Indian Market goes up to 131-133 INR.
