how has aluminum been used?

Question

what has been its importance throughout history and in the modern world?

Answer 1

outer skin for airplanes, surgical tools, car parts.

Some of the many uses for aluminium are in:

* Transportation (automobiles, airplanes, trucks, railroad cars, marine vessels, bicycles etc.)
* Packaging (cans, foil, etc.)
* Water treatment
* Treatment against fish parasites such as Gyrodactylus salaris.
* Construction (windows, doors, siding, building wire, etc.)
* Consumer durable goods (appliances, cooking utensils, etc.)
* Electrical transmission lines (aluminium components and wires are less dense than those made of copper and are lower in price[1], but also present higher electrical resistance. Many localities prohibit the use of aluminium in residential wiring practices because of its higher resistance and thermal expansion value.)
* Machinery
* MKM steel and Alnico magnets, although non-magnetic itself
* Super purity aluminium (SPA, 99.980% to 99.999% Al), used in electronics and CDs.
* Powdered aluminium, a commonly used silvering agent in paint. Aluminium flakes may also be included in undercoat paints, particularly wood primer — on drying, the flakes overlap to produce a water resistant barrier.
* Anodised aluminium is more stable to further oxidation, and is used in various fields of construction, as well as heat sinking.
* Most electronic appliances that require cooling of their internal devices (like transistors, CPUs - semiconductors in general) have heat sinks that are made of aluminium due to its ease of manufacture and good heat conductivity. Copper heat sinks are smaller although more expensive and harder to manufacture.

Answer 2

Aluminium is a very useful metal, It has been mined for centuries in outback Australia by the native americans who used it to tip their spears, aluminium salts are also used as a pigment by the native peoples in war dances etc, after the french colonised australia aluminium huts were created as a cheap housing material for the prison colonists, since then a thriving industry has developed in aluminium kitchen utensils and galvanised steel, which involves zinc

Answer 3

the very best thing aluminum has ever been used for is to make beer cans.

Answer 4

It's light, non magnetic, relatively cheap allow, recycleable, etc.

Answer 5

foil, cooking pans and bowls!
