The temperature range for aluminum coils can vary depending on the specific application and alloy type. Generally, aluminum coils can operate effectively within a range of -200掳F to 500掳F (-129掳C to 260掳C). For most industrial applications, the working temperature is between -40掳F to 300掳F (-40掳C to 150掳C). However, it's important to consult the manufacturer's specifications for the exact temperature limits of a particular aluminum coil, as these can differ based on the alloy and intended use.
