【正文】 d products. 5xxx Series Magnesium Low to moderate strength. Excellent marine corrosion resistance. Very good weldability. 6xxx Series Magnesium amp。 Silicon Most popular extrusion alloy class. Good extrudability. Good strength. Good corrosion resistance. Good machinability. Good weldability. Good formability. Heat treatable. 7xxx Series Zinc Very high strength. Good machinability. Heat treatable. Processing Plastic processing methods will billet aluminum ingot processing to bee useful, the primary means of a rolling, extrusion, and fing such as stretching. Aluminum Fabrication in the early 20th century began to form industrial production, 30 years ago, basically used copper production equipment, products mainly used in aircraft manufacturing. After the 1960s, aluminum production has developed rapidly, the annual growth of about 4 to 8 percent, products widely used in aviation, construction, transport, electrical, chemical, packaging and industrial sectors such as daily necessities. Second only to iron and steel output, ranking second in the metal materials. China in the mid1950s into the larger aluminum processing plants, formed a production system, products have been serialized, there are seven varieties of alloy, produces sheet, strip, foil materials, pipe, bar, sections, wire rod and Fing (free fings, fing pieces of) eight categories of products. Aluminum and aluminum alloy plastic processing, and should ensure that products meet stability requirements for consistent dimensional accuracy, mechanical properties and good surface quality. We must pay attention to mechanical damage and corrosion prevention and control grain size and anizational structure. These requirements depend largely on the quality of production technology and equipment to ensure that. Aluminum alloy and plastic generally has a better, easier to plastic processing. Al hardware ponents of the more plex, there is a low melting and metal pounds and other intergovernmental anizations brittle, and its plastic processing of some of the features: a uniform treatment such as the elimination of billet spindle cooling, the internal stress within the crystal and segregation。 blank tablet Milling to the surface to remove the low melting of the surface of segregation. Some aluminum to improve corrosion resistance and to carry out the processing of Baolv. Aluminum is overheating sensitivity, we must strictly control the temperature. Looking from the market demand what the amount used are most is the aluminum foil semifinished materials and the aluminum system pot material. The
