At its best when the heat is on.  

RAMPTECH® radiators are made from copper and brass for maximum durability on the ramp. Copper and brass radiators have a higher heat conduction rating than aluminum, so it is without question the best material for cooling cores and fins. Tests have shown that of similar core designs, aluminum radiators offer no real temperature drop advantage over copper and brass. Results have shown that core design has more bearing on temperature drop than the material (copper- brass vs. aluminum). Given the same thickness of material, aluminum radiators have a higher strength and can sustain more physical abuse, however, to match the cooling efficiency of copper and brass aluminum radiators must use a thinner wall and more cores. To achieve this, the required physical size would have to increase significantly for the same cooling effect. Additionally, copper and brass radiators can be repaired more easily, with less specialized equipment, and at more locations than aluminum. Copper and brass simply offer the best overall advantage.
