I was just wondering what is the best material to use in drivers? I see some drivers use aluminum, some copper ,some plastic phase plugs. Also some drivers use copper and some use aluminum faraday rings, why? Isn't aluminum a better conductor than copper?

In most cases the phase plug isn't a part of the electrical/magnetic circuit.

But I'd say copper and aluminum are the most popular, effective choices for a faraday ring.
