Key Data Set Information
Location CN
Reference year 2008
Name
Aluminum alloy profile production ; virgin aluminum alloy extruded profiles ; extrusion ; virgin aluminum ingots
Use advice for data set When utilizing this data set for Life Cycle Assessment (LCA), ensure to consider the production route of the aluminum alloy extrusion, which is divided into two parts: 85% originating from the remelting of virgin aluminum ingots and 15% from aluminum alloy rods. Reference statistical data from the Nonferrous Metals Industry Yearbook and use it as the primary source. For non-statistical process data, refer to publicly available literature, research on production processes and technical indicators from typical companies. Estimate related data of bauxite mining, which is linked to aluminum production, using environmental emission data from the mining database within the Umberto 4.0 material flow analysis software. The system boundary for the aluminum alloy extrusion production process should include melting/casting, preheating, extruding, heat treatment, and remelting of process scrap. Due to data availability limitations, the construction, maintenance of aluminum plants, and production and maintenance of smelting furnaces, and other production equipment are not included within the system scope.
Technical purpose of product or process The production process of virgin aluminum alloy extruded profiles is used in various industrial and construction applications. The material produced in this process specifically involves extruding virgin aluminum ingots into profiles. These profiles are utilized in manufacturing components such as window frames, door frames, structural elements for buildings, and parts for the automotive and aerospace industries. The majority of the process begins with the melting of virgin aluminum ingots, while a minor part starts from aluminum alloy rods.

Data selection and combination principles The production process of aluminum alloy extrusion is divided into two parts proportionally, with 85% starting from remelting of primary aluminum ingots and the remaining 15% from aluminum alloy rods.All relevant data are based on the statistical data in the Non-ferrous Metals Industry Yearbook as the main reference. For some non-statistical process data, they come from published literature and research on production processes and technical indexes of typical enterprises. Since the data on ore mining related to aluminum production in China are still not perfect, the data on bauxite mining are estimated by referring to the environmental emission data in the ore mining database of the material flow analysis software Umberto 4.0.
