Molten oxide particles formed craters and pores become nuclear goods. In the absence of oxide impurities, pores and micro pores grind it basically disappeared. For the production of cast aluminum, to reduce the cyanide particularly important impurity foot condition. Because they are typically liquid line and ask solidus of a very large amplitude poor, and in a state of porous condensate, it is difficult to provide a supply void. Oxide film casting failure is the formation of highly fragile surface, cast aluminum mechanical properties of unevenness is precisely due to the presence of these oxide film and cause, if not the oxide film. Inhomogeneity will be reduced, the casting will be better than the performance of repetitive Hebei forging aluminum scrap recycling, using X-ray examination, these oxide films are usually invisible, but do not wait to prevention and must be done again later found to fix. China's aluminum plate material in the development of the demand in the next five years will continue to rise. Is expected in 2015 China's new energy vehicle production and sales will be more than 500,000, more than 12 million passenger demand, then, the demand for aluminum alloy sheet will reach 17 million tons per year. In the next five years, China will usher in a golden period of development of aluminum alloy sheet. Aluminum alloy material is focus on the development of new materials casting industry, but it will also be widely applied to other industries, especially the automotive, aerospace industry, in addition, in recent years, the emergence of 'aluminum and copper' phenomenon, but also to new aluminum materials become the new darling of the cable industry in Hunan recycling aluminum scrap, with the rapid development of these related industries, the development of aluminum alloy material has formed a healthy industrial chain, weight, etc. will also allow the aluminum alloy material come more and more into more industries to replace the previous material, the acclaimed development in these industries, we believe that the aluminum alloy material in the future development will be bigger and better development. _ Sun Shine Shanxi Aluminum scrap recycling scrap metal recycling (certification) _ recycling aluminum scrap recycling scrap metal from the Linyi City Shengxin Limited.
