I believe the heat spreader CAN be aluminum (but it can't be an aluminum can). That's what Ben's is, and it seems to work fine in my car. I haven't done any tests to time how long it takes the heatspreader to reach a given temperature based on a given current. Ian of Zeva uses aluminum. I've tried both aluminum and C110 Copper. Joe's is Copper. The copper heat spreader costs around $40 or so, and the aluminum one is around $5. If the difference is negligible, then I think I would use Aluminum since it's so much cheaper. Copper adds another couple pounds to the weight of the controller too.
