There are about 300 alloys and 1500 varieties of aluminum processed products in China, which is one of the countries with the most abundant product varieties in the world. The formula for calculating aluminum weight is as follows:    aluminum row weight calculation formula (kg) u003d 0.00271 × thickness × width × length aluminum tube weight calculation formula (kg) u003d 0.00879 × wall thickness × (outer diameter-wall thickness) × length aluminum plate weight calculation Formula (kg) u003d 0.00271 × thickness × width × length aluminum rod weight calculation formula (kg) u003d 0.0022 × diameter × diameter × length square aluminum rod weight calculation formula (kg) u003d 0.0028 × side width × side width × length square copper rod Weight calculation formula (kg)u003d0.0089×side width×side width×length square brass bar weight calculation formula (kg)u003d0.0085×side width×side width×length aluminum checkered plate calculation formula: weight per square meteru003d2.96×thickness 1. Aluminum materials can be divided into:   1, architectural aluminum profiles (divided into doors and windows and curtain walls).   2, radiator aluminum profiles. 3. General industrial aluminum profile profiles: Mainly used for industrial production and manufacturing, such as automated machinery and equipment, the skeleton of the enclosure, and the company’s custom-made mold openings according to their own mechanical equipment requirements, such as assembly line conveyor belts, elevators, dispensers, Testing equipment, shelves, etc., are mostly used in the electronic machinery industry and clean rooms.  4. Aluminum alloy profiles for rail vehicle structure: Mainly used in the manufacture of rail vehicle bodies.  5. Mount aluminum profiles to make aluminum alloy picture frames, mount various exhibitions and decorative paintings.  Second, according to the alloy composition, aluminum can be divided into:    can be divided into 1024, 2011, 6063, 6061, 6082, 7075 and other alloy grade aluminum profiles, of which 6 series are the most common. The difference between different grades is that the proportions of various metal components are different. Except for commonly used door and window aluminum profiles such as 60 series, 70 series, 80 series, 90 series, curtain wall series and other architectural aluminum profiles, industrial aluminum profile profiles are not clear. According to the actual drawings of customers, most manufacturers process them according to the actual drawings of the customers. 3. According to the surface treatment, aluminum can be divided into:   1, anodized aluminum material 2, electrophoretic coated aluminum material 3, powder sprayed aluminum material 4, wood grain transfer aluminum material 5, fluorocarbon sprayed aluminum material 6, planed aluminum Materials (divided into mechanical planing and chemical polishing, of which chemical polishing has the highest cost and the most expensive).  A. Classification of aluminum products: rolled products, cast products, non-heat-treated alloys. Pure aluminum alloy (1××× series);    aluminum copper alloy (2××× series);    aluminum manganese alloy (3××× series);    aluminum silicon alloy (4××× series);    aluminum-magnesium alloy (5× ×× series);    aluminum-magnesium-silicon alloy (6××× series);    aluminum-zinc-magnesium alloy (7××× series);    aluminum and other element alloys (8××× series).   They are four-digit aluminum alloys with magnesium and silicon as the main alloying elements and Mg2Si phase as the strengthening phase.   The first digit is a number, which is used to distinguish groups. The last two digits of    are used to distinguish the material grades in the same group series and have no special meaning. The first number of the four-digit system and the four-digit character system designation indicates the category of aluminum and aluminum alloys, and its meaning is as follows:   1XXX series industrial pure aluminum;   2XXX series Al-Cu, Al-Cu-Mn alloy 3XXX series Al-Mn, Machinable pure aluminum;   4XXX series Al-Si alloy;   5XXX series Al-Mg alloy;   6XXX series Al-Mg-Si alloy;   7XXX series Al-Zn-Mg-Cu alloy.   B. Classification of aluminum processing technology: casting materials, heat-treated alloys, non-heat-treated alloys.  C, aluminum processed products classification:    rolled products: sheet (Sheet), plate (Plate), coil sheet (Coil), strip.  Extruded products: pipes, solid bars, profiles (Profiles).   casting products: castings.
