Because they are good conductors of electricity, the best one is Silver but is too expensive to use.
Yes, you can use an aluminum wire. Aluminum does conduct electricity. However, there is a well-known problem with aluminum wire. When exposed to air, the outer layer of aluminum forms a non-conductive oxide. There is resistance to the flow of electricity as it attempts to get through the aluminum oxide coating to the conductive aluminum below. When aluminum wire is used to reduce weight, it is usually welded to another metal that makes a better contact, such as copper. The contact metal is then what is connected.
No. Electricity pylons (usually called "transmission towers" in the US) are basically just supports for the wires. They are specifically designed to be insulated from the electricity flowing through the wires.
Bulk aluminum is usually a silver color. (Think aluminum foil.)
The correct name for AlCl3 is aluminum chloride. This is a compound made from chlorine and aluminum. It is usually a white or yellow salt-like inorganic compound.
Kinda obvious :S Metals (usually aluminum or steel) are used in cars because they are strong and cheap. Expensive sports cars usually have stronger metals (like titanium) but that makes them more expensive. Different metals are used for different purposes, too. The main frame of a car would usually be steel instead of aluminum because it is stronger but delicate pieces would be made of aluminum because strength is not needed but it would be cheaper to make them in aluminum
step up transmission
Both metals have a low resistance to conductivity. They are extremely flexible and do not degrade under electrical transmission as do other metals. They are less expensive than the best conductors, silver and gold.
Yes, a transmission is considered scrap metal! You can sell it to a scrap yard if you wish. They are usually made of some kind of aluminum.

aluminum is usually combined with copper, bronze and magnesium

Usually Metallic substances conduct electricity and heat- They are good conductors of heat because solid particles are close to each other and vibrate frequently. The properties of metals are shiny usually hard and perpetual- some have special attributes such as aluminum which is light and fairly strong.
Usually aluminum, steel or wood.
People are far more likely to recycle if a recycling container is conveniently located where they usually consume their beverages, especially if they don't have to empty it. It might also help to inform them that it takes a tremendous amount of electricity to separate aluminum from bauxite, the ore in which aluminum exists in nature. Much, much less energy is needed to recover aluminum from existing aluminum products, like cans.
The energy used to power a computer is Electrical Energy.
