Generally Shandong Aluminum Die direct manufacturers, cold-rolled aluminum sheet suitable for punching blanking, hot rolling aluminum sheet suitable for stretching. According to different aluminum content of alloying elements can be divided into six series were 1000 Supplying aluminum mold manufacturers, 2000,3000,4000.5000.6000.7000.8000 can be divided into cold-rolled and hot-rolled according to different processes. Depending on the thickness of the sheet and plate can be divided. GB / T3880-2006 standards set forth in what is known as the thickness of 0.2 mm aluminum foil.
