A quantity of aluminum tineed or clad (?)
Material online but not specifically answering my question beyond the general rules of surface conduction.

An absence, in a brief surface read, led to a conclusion there's not a serious difference tween copper m aluminum clad copper. An original patent sez there is a layer of silver molecules between...in 1956, WE.

And the advantage is the AL clad wire is less reactive to insulation at higher temps.

Last question: when soldered is the joint as conductive as copper solder copper ?

Silver melts streams off solder joins copper copper with a low % aluminum.

I used the new aluminum clad wire giving a less conductive result but there are other available reasons for the result so a redo. Maybe a direct conparison.

Is there a potential problem with clad wire in temperature extremes?
Will the layers shed in extreme (-40C) cold or heat (100C)? Or is that
not extreme enough?

Just asking...
