    It is rarely attacked by nitric acid, organic acids or water. It is highly resistant to corrosion.It is light in weight, soft and flexible.It is a soft metal.The melting point of aluminum is about 658°C.It has great stiffness and tensile strength (1,960 kg/cm2).Its specific gravity is about 2.70.It dissolves in hydrochloric acid.

    The next process, called the Hall-Herault process, uses a steel tank, lined with a refractory material with a second layer of carbon, which forms the cathode. The electric current is supplied by carbon electrodes whose lower ends are immersed in the solution obtained by Bayer’s process. These electrodes act as anodes. When a current of…

    The first process is called the Bayer process, in which the alumina in the bauxite is dissolved in a caustic soda solution, filtered and recrystallized to obtain aluminum hydroxide and pure Al2O3. is calcined.

    Aluminum is found in abundance on Earth’s surface. It is available in various forms like oxides, sulphates, silicates, phosphates etc. But it is produced commercially mainly from bauxite (Al2O3, 2H2O), which is a hydrated oxide of aluminum. Bauxite deposits occur almost all over India, and particularly those at Balaghat, Kutni, Chhota Nagpur, Bhopal and Rewa…

    They are available in square cross-sections with sides varying from 5 to 250 mm. They are widely used in all constructions of steel grillwork for windows, gates etc. Commonly used cross-sections have sides varying from 5 to 25 mm with weights of 0.20 kg and 4.90 kg per meter length, respectively.

    This form of steel is available in various shapes and sizes. It is manufactured from sheets of mild steel, which are machine cut and extruded or stretched. Expanded metal is widely used to reinforce concrete in foundations, roads, pavements, bridges, etc. It is also used for lathing material and partitions.
