Questions tagged [copper]
The Element Cu known for its electrical and thermal conductivity, both of which are exploited in EE. THis material is typically what is used in PCB's for the traces and also modern CMOS processes have Cu layers in them due to it's superior conductivity. You also see copper in heat sinks to carry heat away from components.

Reason not to use aluminium wires, other than higher resistance
So aluminium is 3.3 times lighter than copper (8.96 vs 2.70 g/cm3). And its resistance is only 55% bigger. So in weight/resistance ratio it is actually better than copper. Also it is cheaper.
Why ...
