I think we are down to the cost of copper here.
Armored power cables are sometimes made of aluminum if the world price of copper goes sky high.
Aluminum is cheaper than copper and the star washers used to get good contact have improved since aircraft started getting made out of aluminum due to the weight saving.
If you have the copper to hand you had might as well use it.
