Copper vs Aluminum Wiring: Which Is Best? - Monroe ...

Aluminum Wiring. Like copper, aluminum is conductive, so it's become a common material used in the construction of electrical wiring. Unfortunately, aluminum wiring isn't as strong as copper wiring, and it also has a higher thermal expansion coefficient. With that said, there are still advantages to using aluminum wiring.

Aluminum and Aluminum Alloys - NIST

Aluminum is often selected for its electrical conductivity, which is nearly twice that of copper on an equivalent weight basis. The requirements of high conductivity and mechanical strength can be met by use of long-line, high-voltage, aluminum steel-cored reinforced transmis-sion cable. The thermal conductivity of aluminum alloys, about 50 to 60%

Busbars: copper versus aluminum - DCD

Connections rated for use with aluminum are frequently also able to be used with copper and are marked as so, such as AL7CU, a connector suitable for use with copper or aluminum conductors at 75°C. In applications where connections need to be soldered, copper or tinned copper is preferred, as aluminum is difficult to solder.

Copper or aluminium? Which one to use and when?

Aluminum and copper conductors are typically plated with silver or tin. In general, bolted connection of unplated aluminum to copper bus bars is discouraged. The majority of Al to Cu connections are made by applying silver or tin plating to the joint areas of either or both of the conductors.
