Urban Legend #2 Aluminum radiators are better Aluminum units actually do not pass heat better than equivalent brass/copper types. Especially at idle or low speed. Basic Physics 101. But most aftermarket aluminum units are of the oversize variety so it does cool better overall. But we are in an apples and oranges comparison. The aluminum units cost lots more, have far more problems relating to repair and are very prone to long term vibration/stress cracking along with some corrosion issues if not maintained. Some weight savings but from a cost and durability standpoint really not a good "bang for the buck" deal.
