Aluminum

Chemical and Physical Properties:

Aluminum, called as the metal of the era, is a chemical element, the symbol of which is "Al". It has an atomic number of 13 and an atomic weight of 26.97. It is a silver-colored metal. It is one of the most common metals in the world. It is the third most common chemical element after oxygen and silicon. It has a surface-centered, cubic crystal structure. The melting point of aluminum is 650 degrees, the boiling point is 1800 degrees. In nature, it is usually found in the form of bauxite ore and is known for its superior resistance to oxidation. Aluminum is non-toxic and non-magnetic. It does not spark and does not catch fire, has high electrical and thermal conductivity. Its density is about a third that of copper or steel. Aluminum is about 3 times lighter than iron, but it is almost as durable as steel. It can be easily processed and poured hot and cold. Although it is abundant (7.5-8.1%) in the earth's crust, it is very rare in the free state. The history of the commercial production of aluminum dates back a little more than 100 years. The recovery of aluminum from scrap is an important component of today's aluminum industry. The recovery process is based on simple remelting. This method is much more economical than the production of metal from ore. It spends 5% of the energy used in its production through refining.

Areas of use:

Aluminum has a very wide range of uses due to the technical characteristics it has. It is a metal that cools and absorbs heat easily. Therefore, it finds a wide place in the cooling industry.

The main sectors where aluminum is used are:
construction sector 25%, transportation sector 24%,
packaging sector 15%, machinery sector 12%,
electricity/electronics sector 10%, furniture sector 6%,
and other sectors can be ranked at 7%.Aluminum products are produced by methods such as casting, rolling, extrusion and put into use.
