ã€China Aluminum Network】 Aluminum profiles are made of aluminum rods that are hot-melted and extruded to give different cross-sectional shapes. First, according to purpose can be divided into the following categories: 1. Doors and windows for the construction of aluminum doors and windows (divided into two kinds of doors and windows and curtain wall). 2. CPU radiator special radiator aluminum profile 3. Aluminum alloy shelf aluminum profiles, their difference lies in the different cross-sectional shape, but are produced by hot melt extrusion. Second, according to alloy classification: Can be divided into 1024, 2011, 6063, 061, 6082, 7075 and other award winning aluminum profiles, 6 series is more common. The difference between different grades is that the proportion of various metal components is not the same, in addition to the common doors and windows Aluminum profiles such as 60 series, 70 series, 80 series, 90 series, curtain wall series and other architectural aluminum profiles, industrial aluminum profiles without a clear model distinction, most of the production plants are processed in accordance with the customer's actual drawings. Third, according to the surface treatment requirements classification: 1. Anodized aluminum material 2. Electrophoretic coating aluminum material 3. Powder sprayed aluminum material 4. Woodgrain transfer aluminum material 5. Planed aluminum profile (divided into two types of mechanical planing and chemical polishing, in which chemical polishing cost High and expensive
