The combined list of uses of all these elements could be long enough that you will get bored reading it, so we will chop it down to several different parts so it will be easier for students to understand the importance of each metal along with its uses. Let's talk about Zinc's uses; first, Zinc is used in the galvanization process in which the iron and the steel bars are dipped into hot molten Zinc to get it covered in the layer of Zinc.
Speaking of aluminum uses, there is one usage scenario where aluminum cannot be beaten, and that is in the manufacturing of aircraft fuselages. Aluminum is a light metal that can be easily molded into the aircraft's shape while still providing the rigidity of the metal, keeping passengers safe above 30,000 feet. On the other hand, most of the tin cans used to store food and soft drinks are made from aluminum. Most of the kitchen utensils you use in your daily life to cook food are also made from aluminum. The main reason for all of these various kitchen utensils to be made up of aluminum is their low density and non-toxic nature. Also, the thermal conductivity is pretty high, and the same goes for the melting point. Thus, you can use this element in your kitchen without any issues.
All three of these elements are metals but have different molecular mass and atomic weights along with an atomic number. Likewise, all of them have luster, and all three of them are good conductors of electricity. All of them can be used to create a ring due to their resonant property. Lastly, all three of them are malleable and can be rusted easily when they contact air. As a result, all three of them need to have a coating layer to protect them from getting rusted.
Aluminum is the most abundant metal present in the Earth's crust, but it is hard to find it in the uncombined form. During the mining process, we can find it in minerals such as bauxite and cryolite. Also, these minerals which have aluminum in them are called aluminum silicates. There is no doubt that most of us have seen aluminum in our life as it is one metal we get to see everywhere, from our kitchens to airplanes to trash cans.
Aluminum, when not painted, is present in the silvery-white form. It's a lightweight metal that can be easily molded in any shape and size depending on the requirement and stays in that shape for the rest of the time. The melting point of aluminum is 660 degrees celsius. As a result, it is not advisable for containers made of aluminum to put in a microwave oven. On the other hand, speaking of the boiling point, the element will start boiling at 2519 degrees celsius.

We can quickly develop 10 uses of copper as it is present in such a large quantity and has various uses. But the most critical benefit of copper is in the electrical equipment, such as in wiring the electrical component and in the motor coils. Another usage of aluminum is in the field of making coins. It is commonly found across the globe. As a result, its value isn't much, and it is used in the making of coins and other sculptures. The gunmetal also contains copper in it that allows it to quickly harden. The conductivity of both heat and electricity makes it ideal for wires that transmit electricity and signals. These were the major uses of aluminum.
The major uses of aluminum, along with copper and Zinc, are written below.
First, copper is used as lightning protection as it's a good conductor of electricity. It takes the lightning from the top of the building and pushes it down to the ground.
Besides that, aluminum is the one metal that doesn't rust and weighs one-third of steel.
Likewise, Zinc has a self-healing property as its coating self sacrifices itself by going through a galvanic reaction to protect the steel on which it is coated.
These were some of the uses of iron copper aluminum-zinc.
Q1) Find out and write about the two uses of Aluminium?
Answer) In the real world, it is hard to find aluminum in its pure form. You will see several products that use aluminum alloy to form a much harder compound. But when it comes to manufacturing precision tubing, the strong ability to transfer heat makes it an excellent choice for automotive parts such as the engine, AC, and solar market industry. Aluminum is lightweight and is used to carry energy for a longer distance.
But due to its poor electrical conductivity, the manufacturers need to mix it with other metals such as copper to get the job done. The ability to easily withstand the corrosion for a long time without needing any extra touch-ups is the added bonus that makes it ideal for electrical poles and wires.
Q2) What is the Application of Aluminium?
Answer) You might not think of this, but aluminum is also used in construction work, from bridges standing tall on the river to ladders, railings, rods, doors, and wiring. Everything uses aluminum in one way or the other. Aluminum requires low maintenance, and you can paint it easily. Likewise, its property of quickly getting molded into any shape and joining different materials to form a bond leaves us with no reason not to consider it for important construction projects.
We get to see this element daily in our lives. Lastly, aluminum is also used in making computer parts, more specifically CPUs, graphical units, and heat sinks which takes away the heat from the system and cools it down.
