Why is Aluminium so important?
Though highly reactive, it is often present in cooking appliances because it forms a protective layer when exposed to air. This thin white layer coats the metal. The coating prevents it from reacting with oxygen. The non-toxic nature of aluminium makes it safe to use to make cooking tools such as spatulas and whisks.
Countless objects that simplify as well as increase the quality of our daily life are partly made of aluminum, For example: CDs, cars, refrigerators, kitchenware, electric power lines, packaging for food and medicine, computers, furniture and aircrafts. We also use aluminum every day and we don't often realize it.
- Other common things made of aluminum like foil, bike frames, ladders, mail boxes, staples, nails, computer parts, golf clubs, sinks, faucets, screen door and window frames, patio furniture, pots, pans, gates, fencing, and car rims are all things made of aluminum as well.
- Aluminum gets its name from the mineral alum, which gets its name from the Latin word "alumen" meaning "bitter salt." There are a number of aluminum isotopes, but only two occur naturally: aluminum-27 (stable) and aluminum-26 (radioactive).
- Aluminium foil (or aluminum foil), often referred to with the misnomer tin foil, is aluminium prepared in thin metal leaves with a thickness less than 0.2 mm (7.9 mils); thinner gauges down to 6 micrometres (0.24 mils) are also commonly used.
They also have a very thin layer of their oxides on the surface, which stops air and water getting to the metal, so aluminium and titanium resist corrosion. These properties make the two metals very useful. Aluminium is used for aircraft, trains, overhead power cables, saucepans and cooking foil.
- A beverage can is a metal container designed to hold a fixed portion of liquid such as carbonated soft drinks, alcoholic beverages, fruit juices, teas, herbal teas, energy drinks, etc. Beverage cans are made of aluminium (75% of worldwide production) or tin-plated steel (25% worldwide production).
- Most spinnable tempers and alloys of aluminum dent, ding or scratch more easily as compared to steel. Steel is strong and less likely to warp, deform or bend under weight, force or heat. Nevertheless the strength of steel's tradeoff is that steel is much heavier /much denser than aluminum.
- Mild steel shows a ductile-brittle transition at around -60 °C. Results for aluminium show that it become slightly less ductile as the temperature is increased, and all the values for impact energy lie between the ductility of copper and the brittleness of acrylic.
