Aluminium scrap classification

Aluminium scrap is divided into two categories: the new aluminium scrap and old aluminium scrap. The former refers to the aluminum processing and casting production enterprise in the process of manufacturing products produced by the technology of waste and scrap due to unqualified composition, performance products, they are generally made from recycled smelting production enterprises themselves the original brand alloy, there is also a part of the form to do processing to circulate the required casting aluminum electrolytic plant, such new waste when scrap aluminum statistics is not statistical. Old waste refers to the acquisition of scrap aluminium and aluminium scrap from the society, such as the renovation and decoration building replaced the old aluminum doors and Windows, automobiles, electrical appliances, machinery, structure of aluminum, aluminum cans and all kinds of aluminum containers scrap, maturity or grid aluminum conductor and metal parts, old aluminum kitchen utensils and appliances, etc., but also including semi-finished products in aluminum, the finished aluminum products processing waste and scrap. Such as machining aluminum doors and Windows, deep drawing cans, castings and forgings which is caused by waste materials, such as pieces of scraps and waste.

Usually said after waste aluminum or miscellaneous scrap aluminum is a kind of waste aluminum. Most of them used in the production of recycled aluminum alloy/non-ferrous opportunities: aluminum alloy profiles, a small number of components of a single low content of impurities of waste were used for smelting specific composition of high grade aluminium alloy, such as 1350 aluminum scrap wire and cable can be a lot of 1350 alloy used in smelting, waste aluminum cans can be directly 3004 alloy smelting, aluminum doors and Windows can be used for melting scrap 6063 alloys, but for the sake of accurate setting elements must add a certain amount of the original aluminum ingots or additive alloy elements.
