The main raw material component of industrial aluminum profiles is aluminum, which is generally used in aerospace, shipping, construction, electronics industry, transportation, and other industries. With the development of the aluminum industry getting better and better, there are many types of industrial aluminum profiles on the market, how do we distinguish the quality of industrial aluminum profiles? Oxide film thickness: The thickness of the oxide film is not enough, and the surface of aluminum is prone to rust and corrosion. The national standard for architectural and industrial aluminum oxide film thickness should not be less than 10 microns. Main chemical composition: If a large amount of waste aluminum is mixed into the raw material, industrial aluminum profiles can greatly reduce the cost, but it will lead to unqualified industrial aluminum chemical composition and seriously endanger safety engineering. Dimension drawings with approximately the same thickness distribution: cross-sectional size, width, and center hole, but the wall thickness varies greatly, and can also be quite different weights, and the price will also vary greatly. Manufacturer: The raw materials, production process standards, and quality of large aluminum profiles are strictly controlled. Although some small factories have low prices, they cannot guarantee quality.

The current industry is not only a competition product but also an era of competition services. To provide customers with better products and related services, when the factory produces and processes products, each step must strictly abide by the specifications, to ensure that the quality reaches the qualification To make customers satisfied, we can have long-term development. The following editors will talk about what should be paid attention to when producing aluminum profiles?First,Timeliness of heat treatmentWhether it is producing ordinary profiles or industrial aluminum profiles, the temperature in the furnace must be controlled within the specified range, and it can be released after being kept at this temperature for three hours. After the product is taken out of the furnace, the fan must be turned on to blow it for some time to cool it. This process should be inspected by the quality inspector. Second, check the quality of the processed products After processing the product, the aluminum profile manufacturer must also check the product, whether the surface of the product is smooth, without oxidative corrosion or related defects, and whether the curvature and twist of the cut profile are kept within an acceptable range. Third, the product clean packaging in timeFor products that pass the quality inspection, the factory should package the products according to the processed size. When packaging, it must be very strict. Only after the packaging is completed can it be guaranteed that there will be no scratches or scratches during transportation.

Customers who use a lot of industrial aluminum profiles have always been very concerned about the processing of industrial aluminum profiles. The price of industrial aluminum profiles is very transparent. Those who purchase industrial aluminum profiles for a long time know that the pricing model of industrial aluminum profiles is "aluminum ingot price + processing fee". The price of aluminum ingots in various regions of the country will not differ too much. The difference is mainly in the processing fee. Let’s take a look at how much aluminum processing costs are. Three factors affecting the processing cost of aluminum profiles: 1, see the difficulty The larger the cross-section, the higher the accuracy requirements, the more complicated the processing procedure, the higher the relative price 2, see what kind of surface treatment the finished product is There are spraying, electrophoresis, sandblasting, etc., different surfaces require different prices 3, look at the packaging of industrial aluminum profiles Separate package cotton, film, plastic bag, shrink film, kraft paper, carton and other different packaging methods, the relevant costs also vary

Industrial aluminum profiles are widely used in all walks of life, but you may never have a systematic summary of the specific industries that have been developed and applied. Today, the editor will take you to summarize the industries in which industrial aluminum profiles are applied. The first is the application of aluminum profiles in transportation: The transportation industry is a necessary part of life, is to improve the quality of life, and One of the important factors of quality of life. The current transportation industry mainly includes passenger and cargo transportation by plane, high-speed railway and double-decker passenger transportation, heavy-duty freight transportation, underground railway; passenger and cargo transportation by automobile, motorcycle, and bicycle, passenger and cargo transportation by ship, etc. These vehicles require aluminum profiles for support. Let us analyze: the development and application of aluminum profiles in the railway, automobile, motorcycle, bicycle, and shipbuilding industries. 1. Application of aluminum profiles in ship transportation The use of aluminum alloy profiles in shipping vehicles has to be calculated from the 1890s, and there have been more than 100 years of Rexroth. Nowadays, aluminum alloy profiles are widely used in ship vehicles, and aluminum type vessels are developing faster and faster. 2. Application and development of aluminum alloy profiles in aircraft Aluminum alloy profiles also have great development in the aerospace industry because of their lightweight, strong plasticity, corrosion resistance, and ease of assembly. Large-scale special aluminum alloy profiles have become one of the important subjects in various local competitions. At present, many complex overall large-scale special aluminum alloy extrusion profiles have become indispensable and important structural materials in the aerospace industry. For example the aluminum plates and aluminum profiles required for each passenger aircraft require about tens of tons, and the outer shell of each aircraft requires high-quality aluminum alloy profiles. The skeleton of the aircraft needs to be covered with aluminum alloy, and the main skeleton needs to be supported by extruded profiles... Many countries have established research institutes to study the application of aluminum profiles on aircraft. 3. Development prospects of aluminum profiles on railway vehicles In recent years, our railway vehicles are developing towards lightweight, large size, double deck, high speed, safety, energy-saving, comfort, multi-function, low cost, and long life. Along with this, the requirements for car bodies made of aluminum profiles have gradually increased. Therefore, aluminum profiles for railway vehicles are also developing in the direction of large-scale integration, light-weight hollow walls, universal standardization, high performance, multi-function, energy saving, safety, cost reduction, improved material utilization, and production ef...

1. Electrolytic aluminum price fluctuation In May 2020, domestic aluminum prices continued to rise strongly. In May, the average spot price of Antaike East China aluminum ingots was 13,178 yuan/ton, up 1102 yuan/ton or 9.1% month-on-month; the average spot price of south China aluminum ingots was 13,272 yuan/ton, up 1116 yuan/ton or 9.2% month-on-month; Henan aluminum ingots The average spot price was 13,205 yuan/ton, up 1107 yuan/ton or 9.1% month-on-month. Starting situation According to statistics from Antaike, in May 2020, China's electrolytic aluminum construction capacity was 40.795 million tons/year, an increase of 0.5% from the previous month, and the operating capacity was 36.519 million tons/year, an increase of 0.5% from the previous month. The newly invested electrolytic aluminum production capacity of 120,000 tons per year was mainly contributed to the commissioning of Yunnan Aluminum and Yunnan Shenhuo's new projects. In the month, the electrolytic aluminum production capacity was converted to 40,000 tons/year, and the production of electrolytic cells was repaired in the early stage. Aluminum prices continued to operate at a high level, and high profits stimulated electrolytic aluminum enterprises to actively produce, and there was no news of production cuts in May. A Take estimated that China's electrolytic aluminum output in April was 2.997 million tons, an increase of 0.8% year-on-year, and the average daily output was 99.99 million tons. The operating capacity has only increased but the output of electrolytic aluminum has maintained a slight upward trend. The output of electrolytic aluminum in May is expected to be 3.105 million tons, an increase of 2.1% year-on-year, and the daily output will exceed 100,000 tons. Cost change A Take estimated that the weighted average complete cost of China's electrolytic aluminum industry in May 2020 was 11,944 yuan/ton, down 346 yuan/ton from April. During the procurement and use of this raw material, the price of alumina declined, with an average monthly decline of 210 yuan/ton in the north and 180 yuan/ton in the southwest. Coal prices rebounded in May to raise self-provided electricity prices. Prebaked anode prices continued to fall under pressure. The theoretical profit level of the electrolytic aluminum industry reached 95% that month. The profitability of low-cost companies is considerable. Antaike expects that due to the rebound in alumina prices in June, the cost of electrolytic aluminum will rise accordingly, but aluminum prices are also running at a high level, so the high profits of the industry will continue to be maintained. 2. Alumina price fluctuation In May 2020, domestic alumina prices showed a slight upward trend. Antaike's average spot alumina price in May was 2198 yuan/ton, down 26.5% year-on-year and up 2.7% month-on-month. In May, ATK's national average alumina price was 2,202 yuan/ton, do...
