Misunderstandings in purchasing aluminum profiles

Aluminum profiles are aluminum rods that are extruded to form aluminum materials of different shapes through different degrees of heat melting. Aluminum profiles are widely used and are often used in construction, home improvement and industry. Here, I will introduce you to the relevant knowledge of aluminum profile and the price of aluminum profile: 　　1. Features of aluminum profile 1. The density of corrosion-resistant aluminum profile is only 2.7g/cm3, which is about the density of steel, copper or brass (7.83 respectively) g/cm3, 8.93g/cm3), 1/3. Under most environmental conditions, including air, water (or salt water), petrochemicals, and many chemical systems, aluminum can show excellent corrosion resistance.　　2, electrical conductivity 　　 aluminum profile is often selected because of its excellent electrical conductivity. On the basis of equal weight, the conductivity of aluminum is nearly twice that of copper.　　3. Thermal conductivity 　　The thermal conductivity of aluminum alloy is about 50-60% of copper, which is beneficial for the manufacture of heat exchangers, evaporators, heating appliances, cooking utensils, and automobile cylinder heads and radiators.　　4, non-ferromagnetic 　　Aluminum profile is non-ferromagnetic, which is an important feature for the electrical and electronic industries. Aluminum profiles are not spontaneously combustible, which is important for applications involving handling or contact with flammable and explosive materials.　　5. Machinability 　　The machinability of the aluminum profile is excellent. In various deformed aluminum alloys and cast aluminum alloys, as well as in the various states that these alloys have after being produced, the machining characteristics vary considerably, which requires special machine tools or technology. '6. Formability' The specific tensile strength, yield strength, ductility, and corresponding work hardening rate govern the change in allowable deformation.　　7. Recyclability 　　Aluminum has extremely high recyclability, and the characteristics of recycled aluminum are almost the same as primary aluminum.　　Second, aluminum profile specifications: 　　 aluminum alloy door and window profile specifications mainly include: 35 series, 38 series, 40 series, 60 series, 70 series, 90 series and so on. The so-called 35 and 38 refer to the width of the main frame of the aluminum alloy profile being 35 mm and 38 mm respectively. Sealing balconies usually use 70 series or 90 series. If it is less than 70, the firmness is difficult to guarantee. 3. Price of aluminum profile: The production process of aluminum profile mainly includes three processes: casting, extrusion and coloring (coloring mainly includes: oxidation, electrophoresis coating, fluorocarbon spraying, powder spraying, wood grain transfer, etc.), the color is average Available in silver, black, bronze, golden and so on. The price of aluminum profiles is high or low, generally speaking, it is mainly affected by the main factors such as its model series, different uses, and different brands. The price of aluminum profiles is generally in the thousands, and the price range is generally about 14,000-50,000 yuan/ton.
The average consumer is always looking for ways to save money while finding out solutions, is designed for killing two birds with one stone, providing a perfect solution to custom aluminium extrusion problems.
