The differences between Aluminum and Plastic.
What is Aluminum?
The first piece of aluminum was made in 1825, by a Danish chemist, using a combination of two elements, potassium and amalgam. The process was improved in 1847 by using metallic potassium. Then in 1855 the first piece of pure aluminum was made in Paris.
Aluminum is the third most abundant thing in the world, and the most abundant metal in the earths crust. Aluminum is never found by itself, much like gold. There is always something else in it, such as iron, calcium, potassium and magnesium.
If you have the same amount of aluminum and steel, the aluminum will be around a third of the steel’s weight. This means it has a higher strength-to-weight ratio, which means it can be used for things like airplanes, where light metal is a necessity.
Aluminum becomes more important by the day. Household items such as aluminum foil reduce food spoilage. Also, aluminum is a good insulator, meaning you spend less on heating bills.
What is plastic?
Plastic, a material made up of large, organic molecules that can be formed into many different types of products. These molecules are made up of long, chainlike molecules. There are many ways to use plastic. Plastic be as hard as steel, transparent, light, and even elastic. This allows plastic to be used in many different ways. Currently, there are about 50 types of plastic. Plastic is moldable, meaning you can it can mold into different shapes. This is because plastic is made from fossil fuels. Almost everything contains plastic. The car you drive contains plastic, the telephone, the floor. It may not be all plastic, and you might not even know it, but there is some plastic in almost everything.
Plastic, unlike wood, does not rot. This makes it useful for long lasting items. Plastics are generally cheap to produce, but they take up fossil fuels, a non-renewable energy source. Plastic is lighter than steel, and can be as hard as steel if reinforced with glass or other fibers.
Plastic has a history going way back. Back in the Egyptian days, they used natural plastic to mold bowls for soaking the wrappings around mummies. Animal horns contain natural plastic, and people have been making combs and other things for years. It took them until 1839 to accidentally create a type of rubber, which in turn lead them to create the first type of plastic in 1862. After that, they soon started to find a way to replace the ivory billiard balls.
