You can't prescribe a "General" use for these Metals. They have too many uses. For example:
Copper...Wire, Pennies, Roofing, Art Works...
Aluminum....Wire (in the past), Structural Materials, Foil, Airplane Components....
Silver is, then copper, then gold, and then aluminum. Copper is used for wiring because it is cheaper than silver. Aluminum is not used very much anymore because it can be dangerous when installed improperly.
Yes, it is. It is better than aluminum, but not as good as copper. Aluminum is often used in heat sinks, though, because it is cheaper than gold or copper.
Mainly aluminum because of its light weight. Other metals (steel and copper predominantly) as needed.
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.
A copper cloud was used to hide the burning of allomantic metals. This was used to hide skaa half-breeds from the empire as well as a way to prevent soothers and rioters from affecting their emotions.
Aluminum and copper
Silver is, then copper, then gold, and then aluminum. Copper is used for wiring because it is cheaper than silver. Aluminum is not used very much anymore because it can be dangerous when installed improperly.
Copper is preferable to aluminum and the size of wire should be the same or the next size down if copper is used.
Copper is almost always used in car wiring.
aluminum and copper
No, they used to be made from copper or brass.
copper or even more often brass Copper and aluminum are used in house wiring. Aluminum is typically used in the entrance cable and copper for everything past the breaker panel. Aluminum was used for house wiring a few decades ago but it was linked to numerous electrical fires because the connections would weaken over time.
Copper and aluminum used for electric wires
But we do, we do. Copper, Aluminum and other metals are used in many components because they ARE conductors. For example Copper is used in inductors & transformers; Aluminum is used as the plates of most capacitors.
Copper and aluminum are good conductors. Other conductors like silver aren't used to make electric wires because copper and aluminum are cheaper but have the same properties.
an alloy
mostly copper and aluminum
