【正文】 foil consumption quantity assumes the trend of escalation. Our country aluminum material expense peak after 2021 arrives, and achieves the peak in 2021, the year demand surpasses 10,000,000 tons. But the present our country aluminum sheet strip consumption quantity, average per person expends the world average level 1/2, the board strip expense is the developed country 1/101/34, high accuracy aluminum sheet strip dependence import solution. Moreover the import volume large scale is growing every year, expends the growth movement to be obvious, therefore the market prospect favors. The effects of alloying elements The properties and characteristics of aluminum, such as density, conductivity, corrosion resistance, finish, mechanical properties, and thermal expansion, are modified by the addition of alloying elements. The resulting effect depends upon the principal alloying elements used, as detailed in the table below. Wrought Alloy Designation Major Alloying Elements and Typical Alloy Characteristics 1xxx Series Minimum 99% aluminum High corrosion resistance. Excellent finishability. Easily joined by all methods. Low strength. Poor machinability. Excellent workability. High electrical and thermal conductivity. 2xxx Series Copper High strength. Relatively low corrosion resistance. Excellent machinability. Heat treatable. 3xxx Series Manganese Low to medium strength. Good corrosion resistance. Poor machinability. Good workability. 4xxx Series Silicon Not available as extruded products. 5xxx Series Magnesium Low to moderate strength. Excellent marine corrosion resistance. Very good weldability. 6xxx Series Magnesium amp。 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. Therefore the positive coal group plans product in the near future for hot rolling aluminum volume semifinished product, aluminum plate, decoration aluminum sheet, PS version base, forward for aluminum system pot material. The aluminum system pot material is this plan goal product. initially enters the aluminum processing according to the investigation and study situation and the expert opinion as well as the positive coal group the actual situation, plans to use c
