What is the difference between aluminum alloy and copper
1, from the color of the core can be directly distinguished, the color difference between aluminum and copper is very big.
2, under the same power load, because the carrying capacity of aluminum is much less than copper, so the diameter of aluminum wire is greater than copper wire, such as 6KW electric water heater, copper core 6 square is enough, aluminum wire may want to 10 square.
3. The price of aluminum is much lower than that of copper, so the cost of aluminum cable is lower than that of copper cable when the power supply requirements are met at the same distance. Aluminum cable can also reduce the risk of theft (because the recovery price is low).
4, aluminum alloy can do overhead bare wire, generally steel core aluminum stranded wire, copper cable is used for buried wire, generally is not used for bare wire without insulation layer.
5, as for the comparison of good and bad mainly depends on the use, comprehensive environmental factors, social factors (such as theft, etc.), design requirements (current is too large to meet the existing model of aluminum wire, often seen in low voltage and high power load), capital budget and many other factors.
