Basic Information
1. The element aluminum can be also called "aluminium". Aluminum is theAmerican and Canadian spelling, while aluminium is preferred outside NorthAmerica.
2. Aluminum is the most abundant metal and the third most abundant elementin the Earth's crust.
3. Aluminum is the second most widely used metal, while the first is iron.
4. The primary source of aluminum is the ore bauxite.
5. Four tons of bauxite produce one ton of aluminum, which is enough tomanufacture 60,000 beverage cans.
6. China, Russia, and Canada lead the world in smelter production ofaluminum.
7. Aluminum was at one time more valuable than gold.
Facts About Properties
1. Aluminum is often used as an alloy.
2. Aluminum is one of the most difficult metals to refine, since it is oxidizedrapidly and its oxide is extremely stable.
3. The extremely thin layer of oxide formed rapidly in the air provides excellentcorrosion protection for aluminum.
4. Aluminum has a good strength, and four six-packs (24 cans) can hold a4,000-pound aluminum-bodied sedan.
5. Aluminum is lightweight, with a density one third that of steel, making iteasier to handle and less expensive to ship.
6. Aluminum has a high thermal conductivity and high ductility.
7. Aluminum is a very reflective metal, making it very useful in home decoritems. It reflects about 92% of visible light, and about 98% of infrared rays.
8. Aluminum is non-sparking, making it great using in explosive materials orhighly flammable environments.
9. Aluminium cans are the only container allowed in the Himalayas, Nepal,since they crush easily and are light.
Facts About Recycling
1. Aluminum can be recycled over and over again with the same physicalproperties as the original aluminum.
2. Used aluminum beverage cans are the most recycled item in the U.S..
3. Every minute over 100,000 aluminum cans are recycled in the U.S.
4. Aluminum cans account for less than 1% of solid waste stream in the UnitedStates.
5. Recycling aluminum creates 97% less water pollution and 95% less airpollution than producing new aluminum from virgin ore.
6. Recycling aluminum saves 95% of the energy that producing it from virginbauxite ore.
7. The energy used for making one can from virgin ore can be used for making20 cans from recycled aluminum.
8. The energy saved by recycling 1 ton of aluminum can serve a typical homefor 10 years.
