Aluminum is a light metal with good conductivity, thermal conductivity and corrosion resistance. At the same time, the machinability of aluminum alloy is better than that of traditional metal materials.
Usually the thickness of the hot-rolled sheet is 6-8 mm. The minimum thickness is 2.5mm-3.0mm. Due to the large temperature drop during the hot rolling process, it is difficult to continue the hot rolling to a thinner thickness, while the cold rolling easily causes the rolled piece to continue to become thinner.
