Aluminum foil allows car manufacturers to significantly reduce the weight of car radiators. This in turn saves the vehicle's fuel requirements, thereby reducing emissions.
There is a place for cost-effective aluminum foil fin heat exchange units in air conditioning of shops and offices, theatres, ships, refrigerated trucks, trains etc.
Starting at 50µm, foil material thickness reaches 250µm (slightly above the strict "foil" thickness designation). The brazed tape used in heat exchangers is a similar material, but thicker, up to 2 mm thick.
The barrier properties and heat reflectivity of aluminum foil are widely used in building panels, adding to the thermal insulation properties of modern building systems.
In electrical cables, aluminum foil helps provide long-term insulation from moisture and naturally occurring corrosive elements above and below ground.
Aluminum foil also acts as an insulator, preventing magnetic and radio frequency emissions associated with cables. As a jacket for fiber optic cables, aluminum foil uses its conductivity to act as a "tracer" to test the integrity of the cable link and help provide the long-term protection each cable requires.
