Aluminum Sheet of Metal

aluminum sheet of metal

Aluminium is named after alumina, or aluminium oxide in modern nomenclature. The word "alumina" comes from "alum", the mineral from which it was collected. The word "alum" comes from alumen, a Latin word meaning "bitter salt".The word alumen stems from the Proto-Indo European root *alu -  meaning "bitter" or "beer".

British chemist Humphry Davy, who performed a number of experiments aimed to synthesize the metal, is credited as the person who named aluminium. In 1808, he suggested the metal be named alumium.This suggestion was criticized by contemporary chemists from France, Germany, and Sweden, who insisted the metal should be named for the oxide, alumina, from which it would be isolated. In 1812, Davy chose aluminum, thus producing the modern name.However, it is spelled and pronounced differently outside of North America: aluminum is in use in the U.S. and Canada while aluminium is in use elsewhere.

Aluminum General USE

Aluminium is the most widely used non-ferrous metal.The global production of aluminium in 2005 was 31.9 million tonnes. It exceeded that of any other metal except iron (837.5 million tonnes).

Aluminium is almost always alloyed, which markedly improves its mechanical properties, especially when tempered. For example, the common aluminium foils and beverage cans are alloys of 92% to 99% aluminium.The main alloying agents are copper, zinc, magnesium, manganese, and silicon with the levels of other metals in a few percent by weight.

Aluminium can

Some of the many uses for aluminium metal are in:

Transportation (automobiles, aircraft, trucks, railway cars, marine vessels, bicycles, spacecraft, etc.) as sheet, tube, and castings.

Packaging(cans, foil, frame of etc.).

Food and beverage containers, because of its resistance to corrosion.

Construction (windows, doors, siding, building wire, sheathing, roofing, etc.).

A wide range of household items, from cooking utensils to baseball bats and watches.

Street lighting poles,sailing ship masts, walking poles.

Outer shells and cases for consumer electronics and photographic equipment.

Electrical transmission lines for power distribution ("creep" and oxidation are not issues in this application as the terminations are usually multi-sided "crimps" which enclose all sides of the conductor with a gas-tight seal).

Heat sinks for transistors, CPUs, and other components in electronic appliances.

Substrate material of metal-core copper clad laminates used in high brightness LED lighting.

Light reflective surfaces and paint.

Pyrotechnics, solid rocket fuels, explosives and thermite

Production of hydrogen gas by reaction with water or sodium hydroxide.

In alloy with magnesium to make aircraft bodies and other transportation components.

Cooking utensils, because of its resistance to corrosion and light-weight.

Coins in such countries as France, Italy, Poland, Finland, Romania, Israel, and the former Yugoslavia struck from aluminium or an aluminium-copper alloy.

Musical instruments. 

Some guitar models sport aluminium diamond plates on the surface of the instruments, usually either chrome or black. Kramer Guitars and Travis Bean are both known for having produced guitars with necks made of aluminium, which gives the instrument a very distinctive sound. Aluminium is used to make some guitar resonators and some electric guitar speakers.

Aluminium is usually alloyed – it is used as pure metal only when corrosion resistance and/or workability is more important than strength or hardness. The strength of aluminium alloys is abruptly increased with small additions of scandium, zirconium, or hafnium. A thin layer of aluminium can be deposited onto a flat surface by physical vapor deposition or (very infrequently) chemical vapor deposition or other chemical means to form optical coatings and mirrors.
