Time Traveler,

Re: "I thought today's aluminum metal wiring already has some small percentage
of copper already."

This is correct ... Current aluminum interconnect technologies have about
.5% copper in with the aluminum primarily to improve electromigration. I
have personally worked with even higher concentrations (2%-3% copper).

Make It So,
Yousef
