There are many ways that we use aluminum in our industries. From engineering to making artificial gems, there are so many uses of this versatile metal that it is impossible to list them all. It is available all over the world and is used as a cost effective substance in almost everything we use. Most of the aluminum metals we use now are alloys. This is to add strength to the metal.
Aluminium oxide is a chemical compound or combination of aluminium and oxygen. Like aluminium, aluminium oxide is a very good thermal and chemical insulator. It can withhold and tolerate a lot of heat. It is a very hard substance and is used as an abrasive and cutting tool, in mining and polishing. Its most common use is for repairing DVD kits. It is also used as a coating for metal lamps. It reacts with oxygen almost immediately forming a very thin layer of oxide on the top, which prevents the aluminium from weathering further. It is also known as alumina. Aluminium bronzes also protect the aluminium from corrosion.
Aluminium hydroxide is used to make aluminum sulphate which is used as a water treatment chemmical. A large amount is used for making zeolites, coating titania pigments and fire retardents. Other aluminum compounds include aluminium chloride. It is used to make styrene and polystyrene. It is also used in detergents.
Aluminum sulphate is used as a water purifier, for making paper and in water treatment industry. Aluminum sulphate is used to etch lines in printing industry and is used as a mordant for dying textiles. Aluminum is a fine heat conductor so it is used for making coolers for machines. You can make your garden soil more acidic by adding aluminum sulphate to it.
Aluminum is used to make drinks cans and attempts are made to recycle these in return for money. The aluminum from these cans can be remade into alluminum and alluminum alloys for different uses. It can also be recycled into drink cans again. Recycling conserves energy as it takes about 90% less energy to recycle the cans rather than extracting aluminum from its raw form.
Aluminium is also used to make foil, which keeps food warm and protected. Foil can be used to wrap up rooms in winter to keep it warm. A huge sheet of foil, pasted on the insulation board can prevent the heat from escaping. Putting aluminium sheet around an outside light makes the light shine brighter. It can also be used to scrap the rust from your car, with the help of coke.
Aluminum is one of the most important metal of world's economy, which manipulates 60% of the global economy. The worth of aluminum is a recent discovery made during the last 150 years. The Chinese people were the pathfinder in using aluminum since 300 A.D. It is a versatile metal with multipurpose usage. We need aluminum for our vehicles, in our homes and in the outer domain of industries. Today, without aluminum we cannot live our life to the fullest, technically or otherwise.
