Particularly for a Series Landrover, which is a working vehicle, expected to be used on rough roads and in rough conditions, thermal performance is not necessarily the only consideration.
Also important is the physical strength of the core and its ability to withstand vibration, its ability to withstand cleaning grass seeds and other chaff from the fins, and its corrosion resistance. For all of these, copper would seem preferable to alumimium.
