2301 A Review : The Potential of Powder Metallurgy in Recycling Aluminum Chips (Al 6061&Al 7075)

Abstract

Aluminum products are becoming popular and the demand is increasing because of its special properties such as excellent corrosion resistance with good strength, recyclable and low density compared to steel. Currently, two methods used to recycle aluminum chips are conventional and direct conversion methods. Recycling of aluminum chips by the direct conversion methods is relatively simple, consumed less energy and do not harm the environment. The cost of recycled materials is much lower than the cost of primary aluminum production by conventional technique. This paper reviews the recycling technologies of aluminum chips using powder retallurgy technique.
