Cast aluminum-silicon (Al-Si) aluminum-silicon alloy applications (Al-Si) alloy, generally Si content of 4% to 22% due to Al-Si alloys have good casting properties, such as mobility, airtight good, shrinkage and small warm tendencies, after deterioration and heat treatment, has good mechanical properties, physical properties, corrosion resistance and moderate machining performance, the old battery recycling factory, is the largest species in casting aluminum alloy, use The most widely used class of alloys. Al-Si alloy casting common features and application as follows: cast aluminum and zinc (Al-Zn) alloy applied to Al-Zn alloy, due to the solubility in Al Zn big, so when Al in mass fraction greater than 10% When Zn, can significantly improve the strength of the alloy. Although such alloys to natural aging tendency of large, Weihai old battery recycling, without heat treatment can get higher strength, but the disadvantage of these alloys is poor corrosion resistance, high density, prone to hot cracking during casting. Therefore, these alloys are mainly used in the manufacture of the instrument shell-casting Parts. Al-Zn alloy casting common features and application as follows: From 2007, the Spring Festival, a week before the total stock of domestic dominance is only 50,000 tons, after the holiday jumped to 163,000 tons, an increase of up to 226%, while in 2008 over the same period stocks increased 184,000 tons from the 137,000 tons, an increase of only 34%, compared with 08 years before the Spring Festival domestic stocks appear more moderate growth. Stock incremental changes directly affect the price of aluminum. 2007 stock surge has led to aluminum prices continued to drop after the holiday, until mid-March only stop the decline, decline in 13 trading days up to more than 800 yuan / ton. 2008 Festival domestic aluminum prices relatively stable trend, Shanghai and Guangdong and Shenzhen stock aluminum flat nearly five days, while the month Shanghai aluminum contract rose 220 yuan.
