Why Metal Is So Useful

Metal is a marital that is very useful to many different people for a variety of reasons. This is because it can be easily manipulated and shaped in order to make things like strong tools. Metals such as steel and iron are regularly used for the purpose of constructing large items such as cargo ships, skyscrapers, and bridges. The more rare metals, such as platinum, silver, and gold, of course have a higher value and so are used to make more intricate pieces, such as jewellery.

How It Is Used

Metals that are shiny and look good, such as gold, silver, and copper, are used to produce things like coins, jewellery, and decorative art. The stronger, more robust metals, like allos of metal and iron, are used to construct things like trucks, trains, cars, ships, and buildings.

Metals Used In Everyday Life

An example is copper, which is for electrical wiring and other purposes. Silver is used for electronic circuits, and gold is often used within certain pieces of computer technology. The metal, aluminum is often used to make aeroplanes, trains, automobiles and ships due to it being lightweight. 

How Is Lead Used?

The metal lead is used for a number of different products both around and in our homes. It is found in cosmetics, ammunition, batteries, gasoline, solders, plumbing material, pipes, ceramics, and paint. Lead can enter into the environment through these products and through how they are used.

For the purpose of producing high speed bullets, lead jackets are placed around regular bullets. The reason why it is used is because of how dense it is – thus giving a greater amount of mass to the bullet. This results in a greater amount of kinetic energy being produced. 

How Is Copper Used?

Copper is much lighter than what lead is, which is one reason why it is used to make bullets. It is also very hard. Because of this, copper bullets are less likely to fragment than what regular bullets are. Other uses of copper include jewellery, clothing accessories, motors, and wiring. The reason why it is used in electrics is because of its ability to conduct electricity and heat well. 

How Is Steel Used?

With it being cheap to produce and having a high tensile strength, steel is used for a variety of different purposes, including in the building of skyscrapers, infrastructure, machines, automobiles, trains, ships, tools, weapons, and electrical appliances. The base metal of steel is iron.

How Is Iron Used?

One of the main things that iron is used for is to create steel alloys, such as carbon steels. These contain additives like manganese, tungsten, vanadium, chromium, and nickel. It is these alloys that are used to construct bridges, rifles barrels, cutting tools, bicycle chains, and electricity pylons. Where iron contains between 3 and 5 percent carbon, it is known as cast iron. This is used for pumps, valves, and pipes.
