"24V DC Cooling Fan" aluminum alloy material according to different needs, by adjusting the composition ratio of the material formulation can be obtained in a variety of different features, suitable for different forming, processing methods, applied to different fields. "24V DC Cooling Fan" 5 different aluminum alloys in: AA6061 and AA6063 with good thermal conductivity and work ability, suitable for extrusion process, the fins are widely used in the processing. ADC12 suitable for die casting, but the thermal conductivity is low, so the heat sink processing usually used instead of aluminum alloy AA1070, unfortunately inferior mechanical properties and processing ADC12. AA1050 it has good ductility, "24V DC Cooling Fan" is suitable for stamping process, used for the manufacture of thin fins.
