The production of sheet aluminum takes place when it is passed between very strong and heavy rolls under great pressure. It becomes thinner and longer as it is rolled until the desired thickness is reached. The thickness is usually two inches think.
Somewhat twenty tons of preheated sheets that are twenty feet long and six feet wide are placed in the rolling mills and then rolled to and fro. When this process is done, the metal gets heat-treated and cooled down quickly. This is to give strength to the plates just before the stretching and straightening takes place. This process is referred to as stress relief that builds up during the rolling and heat-treating.
The metal plate is then finally trimmed and aged at the correct temperature until the final properties are developed. It is passed through the breakdown mill once more to reduce the thickness even more and the sheet thickness is then lastly coiled.
The coil sheet gets heated once again in a heated furnace. When it is soft enough, it is ready for cold rolling, which is the last step of the production unless it has to be heat-treated to increase the strength. During this stage, lubrication is added when foil will be produced.
The final product is used for the skins of jumbo jets, spacecraft tanks and containers and storage tanks that hold cryogenic materials. These need to be stored under very low temperatures. The structural sections of ships and rail cars as well as the armor protection of military vehicles and trucks transporting cash are made from this metal.
In the packaging industry, it is used for making cans and many perishable foods are wrapped with foil to protect it during the times it is not refrigerated. In the automobile industry, it is used for bodies of the vehicles as well as license plates. It is also used in home appliances and cookware as well as house gutters, roofing and carports. Road signs are made with this as well as some parts in airplanes.
It is possible to color the plates and even to etch them into certain finishes like wood finishes and other effects. Brightness is polished into it for a shinier effect. Environmental concerns that spring to life are due to the high cost related to the extracting of this kind of material. There is a cost reduction though in the form of recycling efforts.
