Haomei Aluminum

  Haomei are specialized in aluminum rolls sheet metal  manufacturing and export for more than 20 years with advanced producing technology. The technical method of aluminum sheet roll are hot rolling and cold rolling. When it comes to aluminum sheets, the first thing we think of is the cold rolling process. The rolling process below the recrystallization temperature of metals and alloys is called cold rolling. During cold rolling, although the temperature of the rolled piece can be high due to the heat of metal deformation and frictional heat, it has a certain recovery effect, but cold rolling hardening (work hardening) plays a major role in the cold rolling process. Compared with hot rolling, the main feature of cold rolling is that thinner aluminum sheet and strips can be obtained. Usually the thickness of hot rolled slab is 6-8mm. The minimum thickness is 2.5mm-3.0mm. Due to the large temperature drop of the rolled aluminum sheet  during the hot rolling ...
