预计阅读时间：10 分钟May 31, 2019 Aluminum conducts electricity 61 percent as well as copper but weighs 1/3 as much. Because of this, aluminum conductors are less expensive than conductors made of copper. Most aluminum wires made to conduct electricity are made of aluminum alloys. The aluminum AA-1350 series is 99.5 percent aluminum with 5 percent of iron, copper, silicon and ...
Jul 15, 2017 If aluminum is used as a conductor material, its lower conductivity requires a wire size approximately one-third larger than that of a copper wire with the same desired conductivity requirements.

Download Southwire's Voltage Drop Calculator from their calculators page to help with proper sizing.
Jan 03, 2020 The tensile strength of copper is roughly 40% higher than that of aluminum. With a higher tensile strength, copper wiring is less likely to break than aluminum wiring. This is important considering that electrical wiring is often installing by pulling it through ports and feeders. If the wiring is weak or fragile, it may break during installation.
Mar 09, 2018 Ans:- Due to its advantage of low cost and less in weight. Even the copper has 1.7 times conductivity than aluminium conductors, it weights 3.3 times heavier than aluminium. Hence aluminium conductors can considerably reduce the weight for the same amount of power loss compared to copper.
Mar 15, 2007 Aluminum does NOT conduct the same as Copper. Conclusion, before using Alunimum in place of Copper: 1. Check with the AHJ. 2. Check components, Switchboards, Panelboards to see if the UL Listing will accept Alunimum. 3. In boarder line applications, Alunimum may have too much heat-rise. Just my $.02.

of this conductive metal and how to deal with the challenges it presents. Copper, which is priced at 5800 EUR per ton, is currently more than twice as expensive as aluminium, priced at 2272 EUR per ton (as of 01/05/15). The greater availability of raw aluminium compared to copper accounts for this significant difference in price.
