Question

5. Compare copper and aluminium is six aspects?​

Answer 1

Answer:

The difference between aluminum and copper wire is largely in their usage within utilities, resistance, conductivity, weight and cost. Aluminum is in use by the utility companies for the transmission of electricity since the early 1900’s. Aluminum seems to have more advantages over the older copper wire in terms of weight, flexibility and cost, as it is lighter, more flexible, and less expensive.

Aluminum wiring was preferred over copper wiring largely due to the rising factor of the price of copper, and therefore, aluminum wiring was economical. Aluminum alloy building wires, called the 800 alloy, is also used for low voltage feeders, saving on costs when compared to copper, which is also significantly heavier in weight as well. Aluminum building wires have half the weight of copper, with 50% greater area than copper to carry the same current, but aluminum wires need a larger wire gauge than copper to carry the same weight. Increased copper prices have also given rise to the use of aluminum wires during the 1970’s. Aluminum wiring can be just as safe as copper if properly installed, as aluminum wiring is unforgiving in the case of improper installation.
