Industrial aluminum (alloy) profile is widely used, strong versatility, it is known for environmental protection, easy assembly and disassembly, saving time and money.No welding, accurate size, easy to change structure;Assembly work is convenient and fast, high productivity;The surface is treated by anodic oxidation, with high finish, anti-corrosion, no spraying, beautiful and generous, which can improve the added value of the product. Now the price of industrial aluminum profile market is more chaotic, the price gap is very far.The main factors leading to different prices are: Raw material: In order to save the cost of using recycled aluminum, the flatness and surface defects of the produced profiles are seriously exceeding the standard, and even cause the profiles to break. Fujian Shuangheng Group only USES A00 standard aluminum. Homogeneous: The traditional process can not guarantee the uniform distribution of alloy composition, which is easy to cause surface defects and unstable product batches.However, the early investment of homogeneous rod production is higher, and the later production cost will also be higher, so many small manufacturers are unable or unwilling to invest. Fujian Shuangheng Group industrial aluminum profile is produced by homogeneous bar production process, which reduces the die extrusion ratio and extrusion pressure.Improve the surface quality and mechanical properties of finished products. Oxidation: In order to save costs, reduce oxidation time and steps, resulting in substandard oxide film thickness, easy to cause surface damage of profiles, especially in processing, assembly and logistics links. Fujian Shuangheng Group adopts frosted oxidation, the surface is free from defects, the film thickness exceeds national standard by 30%, and the profiles are as bright and clean as new in 20 years. Testing equipment: In order to reduce labor costs, equipment maintenance costs, and technical costs, many enterprises do not have a full set of equipment or equipment itself precision is not high and not regular maintenance, let alone professional personnel and strict procedures.Low product cost, resulting in vicious bidding industry, customers found after buying unsatisfactory. Fujian Shuangheng Group spectrometer and tension, end face, hardness, film thickness tester and other imported series of complete testing equipment, 12 strict testing procedures, professional testing personnel. Suggestion: Choose the main aluminum suppliers Choose the main supplier of aluminum, are generally not engaged in this industry more than 10 years, especially the processing experience of the factory, has very rich practical experience, the product quality and performance have good understanding and master, can according to the different field of application, issue a reasonable framework scheme design, choose a convenient and practical way of fitting connection, recommend to customer demand for a good cost performance products.

At high temperature, the aluminum profile has high plasticity and low resistance, coupled with the intensified atomic diffusion process and complete recrystallization, which is beneficial to the improvement of the structure.Thermal deformation is the most effective way to change the as-cast structure of aluminum profiles when the 3-direction compressive stress is dominant.The following favorable changes of as-cast microstructure can be obtained with appropriate deformation. (1)The general thermal deformation is accomplished through repeated deformation of multiple steps.As both hardening and softening processes occur simultaneously in each strand.The large columnar grains were broken by deformation of industrial aluminum profiles.At the same time, it can also make some small cracks can be healed. (2)Due to the hydrostatic pressure in the stress state, bubble welding can be promoted in the as-cast structure, shrinkage cavity compaction, loose compaction and densification can be changed into a relatively compact structure. (3)Due to the enhanced thermal motion ability of high temperature atoms, under the action of stress, the free diffusion and heterdiffusion of atoms are conducive to the relative reduction of the ingot chemical composition non-uniformity. By thermal deformation, the ingot structure improves the deformed (or processed) structure, resulting in higher density, uniform fine equiaxial grains, and more uniform chemical composition, thus significantly improving the plasticity and resistance index. Shuangheng Group is located in Quanzhou,Fujian,China,is a high-tech comprehensive enterprise including scientific research, manufacture, sale, international trade of photovoltaic solar energy, Ground Screws,Aluminum Mounting System, new building materials, industrial aluminum profiles, various aluminum products ect.

According to the classification of USES, aluminum profiles can be roughly divided into nine categories: 1.industrial aluminum, general industrial aluminum refers to: mainly used for industrial production and manufacturing, such as automatic mechanical equipment, the framework of the cover and each company according to their own mechanical equipment customized mold, such as aluminum workbench, pallets, industrial fence, aluminum rack, equipment cover, and so on. 2. Building aluminum profiles, mainly including doors and Windows aluminum profiles and curtain wall aluminum profiles; 3. Radiator aluminum profiles are mainly used for heat dissipation of various power electronic equipment, LED lighting, and computer digital products, etc. 4. Auto parts aluminum profiles, mainly used for auto parts, connectors and so on. 5. Furniture aluminum profiles are mainly used for furniture decorative frames, desks and chairs supporting parts, etc 6. Solar photovoltaic profiles, solar aluminum profile frame, solar photovoltaic bracket, solar photovoltaic tile coupler, etc. 7. Aluminum alloy profiles of rail vehicle structure are mainly used in the manufacture of rail vehicle body. Aluminum alloy profiles are characterized by light weight, good molding, high strength, corrosion resistance, and recyclability, etc. In recent years, aluminum and aluminum alloys have been widely used in the field of rail vehicles. 8. Aluminum profiles, made into aluminum frame, mounted various exhibitions, decorative paintings. 9. Medical equipment aluminum profiles are mainly used for stretcher frames, medical instruments, medical beds, etc.

Source: Wenhua Finance The global primary aluminium market oversupplied 1.537m tonnes in the January-August period of 2020 and 500,000 tonnes in the whole of 2019, according to a report released by the World Bureau of Metals Statistics (WBMS) on Wednesday. Demand for primary aluminium from January to August was 42.79 million tonnes, up 203,000 tonnes from the same period in 2019. Measured on an apparent basis, the full impact of the national lockdown imposed to contain the COVID-19 outbreak may not be fully reflected in trade statistics. Primary aluminum production rose 3.8% in the January-August period. Overall reported inventories rose at the start of the year but fell in July and August, ending the month 186,000 tonnes above December 2019 levels. Inventories in Shanghai rose steadily at the beginning of the year but fell by 300,000 tonnes in the second quarter, from 251,000 tonnes at the end of August. At the end of December 2019, it was 185,100 tons. LME stocks stood at 1.5502 million tonnes, compared with 1.473 million tonnes at the end of 2019. Significant unreported inventory changes, particularly those held in Asia, are not included in consumption statistics. Overall, global primary aluminum production from January to August 2020 increased by 3.81% compared with the same period last year. Based on increased supplies of imported bauxite and alumina, China's output is estimated at 24.283 million tons, now accounting for about 55% of global output. China's apparent demand increased by 8.9% from January-August 2019, and the production of semi-finished products increased by 6.2%. China will become a net importer of unwrought aluminium by 2020. From January to August 2020, China's net exports of aluminum semi-finished products were 2.778 million tons, compared with 3.294 million tons in the same period last year. Exports of aluminium intermediate goods fell 14 per cent year on year. From January to August, primary aluminium production in the 28 COUNTRIES of the European Union was up 0.5 percent year on year, and production in the North American Free Trade Area (NAFTA) was up 4.5 percent. From January to August, the amount of primary aluminum sought by 28 eu countries fell by 934,000 tons compared with the same period last year. From January to August, global demand increased by 0.48% year on year. In August 2020, the output of primary aluminum was 5,763,500 tons and the demand was 5,461,400 tons.
