The international aluminum price has not taken the usual path. Since reaching a price high of 3,975 USD in March, it has been falling all the way. Yet, oddly enough, global aluminium supplies are continuing to tighten and prices should have been supported. But the reality is that, like most metals markets, demand destruction dominates the market logic and prices are powerless to turn around. 1. Costs have risen sharply Europe is in the midst of an unprecedented energy crisis, with gas supply worries intensifying and electricity prices soaring. The trend of passing natural gas prices in Europe to rising electricity costs will continue, which will undoubtedly be a huge blow to the metal smelting industry, which is very dependent on electricity. It is reported that some aluminium smelters and alumina refineries have been partially or fully closed due to rising electricity prices, making the supply of architectural & industrial aluminum profiles and aluminium-related products fraught with risk. Not only Europe, but the United States is also suffering from high electricity prices. Last week, Alcoa warned that soaring global costs would render as much as 20% of its aluminum capacity unprofitable, and expects to see a strong recovery in prices only in 2023. In addition to electricity prices, China's related production capacity is still unstable due to the impact of the epidemic, and the international shunning attitude towards Russian aluminum products manufacturer is exacerbating the problem of tight supply. 2. The demand side is destroyed Cost is only one of the reasons for the fall in aluminum prices. The other two come from the high exchange rate dollar and Chinese demand. China is the largest consumer of aluminum. Due to the epidemic, downstream industries of aluminum products have been cautious, which has also led to the continued sluggish demand for aluminum products, which also provides a catalyst for demand destruction. To make matters worse, the world has entered a period of rising interest rates, which has also driven the dollar to continue to strengthen. The high exchange rate USD usually has a certain negative correlation with commodity prices. In addition, the increase in interest rates has also weakened the profits of the aluminum trade. In the metals market, many traders buy metals in the form of borrowing, and rising interest rates increase the debt burden. This is undoubtedly a signal to stop the entry for risk-averse people. The weakness of the macro environment has caused aluminum companies to stop production to protect themselves. Alcoa announced last month that it would close its second-largest smelting plant in the United States; Alcoa announced it would cut some production lines, resulting in a loss of $20 million.

The annual International Labor Day holiday is coming, this year our holiday time will be arranged from April 30, 2022 to May 4, 2022, a total of 5 days of small holiday. Our company will resume working hours on May 5, 2022. As the holiday is coming, the price of aluminum profiles and container house may rise or fall to some extent in the next five days. Customers can first consult the products they are interested in and check the details. We will give customers a satisfactory official offer on May 5, 2022. When it comes to the annual International Labor Day, we should actively promote its significance. The significance of International Labor Day lies in the tenacious, heroic and unyielding fighting spirit of laborers through struggle. Winning one's own legitimate interests is the historic progress of human civilization and democracy, and this is the essence of May 1st Labor Day. This is also the biggest reason why people pay attention to Labor Day. Labor creates wealth, labor creates civilization, and laborers are the creators of all civilizations and wealth. Labor is divided into mental labor and manual labor. The mental laborers summarize the experience of physical labor, and the manual laborers realize the vision of the brain hole laborers. . The glory of labor lies in the scientific realization that the development of human civilization is fundamentally the result of the combination of mental labor and manual labor. Finally, I wish every hard worker a happy holiday and Happy International Labor Day!

1. The surface of the aluminum ingot is attached with debris or the composition of the aluminum ingot is segregated. When there are a large number of segregated floats on the surface of the aluminum ingot and the aluminum ingot has not been homogenized or the homogenization treatment effect is not good, there are a certain number of hard metal particles in the aluminum ingot. During the extrusion profiles process, when the metal flows through the working belt, these segregation floats or hard metal particles adhere to the surface of the working belt or cause damage to the working belt, and eventually scratch the surface of the profile; 2. There are sundries on the mold cavity or working belt, and the hardness of the working belt is low, so that the surface of the working belt is injured during extrusion and scratches the profile; 3. There is bare metal or hard inclusions on the discharge track or swing bed, which will scratch the surface of the profile when it is in contact with the profile; 4. When the fork bar sends the aluminum profiles from the discharge track to the swing bed, the profile is bruised due to the excessive speed; 5. Manually drag the profile on the swing bed to cause scratches; 6. During transportation, the profiles are damaged by friction or extrusion Solution 1. Strengthen the quality control of aluminum ingots; 2. Improve the quality of mold repair, the mold is regularly nitrided and the nitriding process is strictly implemented; 3. Use soft felt to isolate the profile from the auxiliary equipment to minimize the contact damage between the profile and the auxiliary equipment; 4. It should be handled with care during production, and try to avoid dragging or flipping the profiles at will; 5. Arrange the profiles reasonably in the material frame and try to avoid mutual friction.

On February 22, the London Metal Exchange (LME) aluminum price hit a multi-year high.The move comes after Russia ordered troops into two breakaway regions in eastern Ukraine, sparking fears of war and sanctions that could affect Russian exports. LME three-month aluminium rose $23.50, or 0.72%, to $3,303 a tonne at 17:00 on February 22, London time, after hitting $3,380 a tonne earlier, down slightly from $3,380.15 in 2008 record high. Russia's aluminum production accounts for about 6% of the world's, rusal was sanctioned in 2018, and aluminium prices rose 35% in a few days.Aluminium prices are up around 17% so far this year after rising 42% in 2021.ING analyst Wenyu Yao said,even with Russian exports unaffected, aluminium remains in short supply. "They were seeing very strong fundamentals before the Russia-Ukraine crisis escalated," she said. Germany suspended the certification of a new Russian gas pipeline and Britain imposed sanctions on Russian banks. The West has responded to Russia's recognition of the two breakaway regions of Ukraine and a speech by Russian President Vladimir Putin suggesting more belligerent targets. Western countries are unlikely to impose sanctions on Rusal, analysts said, as high aluminum prices hurt manufacturing. The shortage has caused aluminium inventories in LME warehouses to fall to 835,125 tonnes from nearly 2 million tonnes in March last year. Premiums for spot aluminium over the three-month contract are close to highs not seen since 2018, and premiums for physical duty-paid in Europe and the US have risen to record highs.

In December 2021, the price of natural gas in Europe hit a new high again, with an increase of more than 16%, and the market is worried that the price of natural gas in Europe will rise further. Energy costs soared, European zinc plants announced production cuts, followed by news of European high-cost aluminum plants cutting production, boosting aluminum prices in London to rise continuously. Compared with the rise in aluminum prices in the first half of 2021 due to rising raw materials, tight power supply, and the impact of supply and demand mismatches and global inflation, the recent changes in aluminum prices are more affected by the European energy crisis. As the price of aluminum ingots has grown, so has the price of aluminum profiles, and the price of many aluminum products has maintained an upward trend since 2021. In recent years, the global demand for aluminum has continued to rise, especially in emerging industries such as photovoltaics, new energy vehicles, and rail transit.The demand for various aluminum rails, aluminum accessories, aluminum extrusion products increases. Whether the scale of production reduction by European aluminum companies can be upgraded depends on whether the gap in natural gas will be further enlarged. Referring to the previous situation of domestic coal prices and electricity in China, if energy prices are allowed to continue to rise, industrial enterprises facing high electricity costs will have to shut down one after another, which will lead to rising inflation and unemployment. In the course of the game, the policy adjustment that may be adopted, energy will face the pressure of correction, and it is also a potential risk for aluminum prices to continue to rise. Considering the impact of unstable supply in Russia, the onset of cold waves, and the interruption of nuclear power, the energy crisis in Europe may continue throughout the winter and into the spring of next year. It is expected that aluminum prices will remain strong in the short term.

1. The difference in grade: Aluminum alloy thermal windows and UPVC windows are suitable for different building consumer groups. Statistics show that UPVC windows are suitable for general low-rise residential buildings. Consumers of this grade of products are often concerned about the product. The quality requirements are not very high, and high-performance thermal insulation aluminum alloy windows are suitable for buildings of various heights and grades, and the quality and life performance can withstand the test of high standards. 2. The difference in performance: The energy-saving effects of the two are similar; but due to the difference in material, UPVC windows are prone to deformation after a period of use, and the sealing performance is not as good as high-performance aluminum alloy windows. 3. Difference in service life: Due to the large difference in material strength, elastic modulus and wear resistance, the service life of high-performance aluminum alloy windows is often longer than that of UPVC window. 4. The price difference: Generally speaking, the price of high-performance aluminum alloy windows is usually higher than that of UPVC window. However, in the long run, although the price of high-performance aluminum alloy windows is high, they have a long service life; while UPVC window are cheaper but have a short service life. Therefore, the overall price ratio is comparable. In summary, high-performance aluminum alloy windows have more competitive advantages.

1. What is the relationship between the specifications of the aluminum profile extrusion press and the cross-sectional diagonal of the profile? The tonnage of the extruder is calculated according to the size of the extrusion force, and the tonnage represents the extrusion force. Common ones are 500t, 630t, 800t, 1000t, 1200t, 1800t, 2500t, etc. The larger the tonnage, the larger the aluminum profile that can be produced, that is, the larger the diagonal. Simply put, the larger the size of the extruder, the larger the diagonal of the aluminum profile can be produced.     2.  How to determine the tonnage of the extruder to be used for aluminum profile production? Extruder is the main equipment for the production of aluminum profiles. The shape, size and appearance quality of aluminum profiles are closely related to the quality of the extruder. There are many types of extruders. When choosing the tonnage of the extruder, it is generally necessary to First calculate the extrusion ratio of the extruder. The extrusion ratio is also called the extrusion coefficient. It refers to the ratio of the cross-sectional area of the extrusion cylinder to the total cross-sectional area of the aluminum profile. It is used to measure the deformation of the aluminum alloy in the production of aluminum profiles. The main parameters of the amount are expressed by the following formula: Λ=Ft/ΣF1 Among them, Ft represents the cross-sectional area of the aluminum ingot after being filled in the extrusion cylinder, expressed in mm²; ΣF1 represents the total cross-sectional area of the extruded profile, expressed in mm²; When the aluminum profile is extruded, the amount of deformation of the aluminum alloy can also be expressed by the degree of deformation: ε=λ-1 If the extrusion processing method is used, the extrusion ratio is limited. The extrusion ratio λ of the aluminum profile and aluminum rod in the first extrusion is greater than 8-12, and the extrusion of the blank for the second extrusion There is no limit to the pressure ratio. The method used to calculate the extrusion ratio above is simply the cross-sectional area of the extruded ingot ÷ the cross-sectional area of the extruded profile. It can also be calculated in other ways, that is, the length of the extruded profile ÷ the extrusion use The length of the ingot. Before determining the tonnage of the extruder, it is necessary to understand the cross-sectional shape of the profile, so as to determine the size of the mold, and then determine the structure of the mold, so that it can be determined whether the extrusion is a hollow profile or a solid profile. These two different types The extruder tonnage required for structural profiles is different. There are many types of extruders. According to the extrusion capacity, they can be divided into small, medium, large and heavy extruders. The extrusion capacity of each type of extruder is limited. The extrusion capacity is usually MN Representation, ...

Recently, the International Aluminum Association (IAI) released a series of new global aluminum industry decarbonization process data inventory reports before the 26th United Nations Climate Change Conference in Glaston, Scotland.The report pointed out that by 2050, the total carbon dioxide emissions of the global aluminum industry need to be reduced by 77% compared with 2018. Among them, the carbon dioxide produced by the production of alumina and electrolytic aluminum will be significantly reduced. The report predicts that aluminum smelting should reduce carbon emissions by nearly 90%. The specific value is from 823 million tons to 90 million tons. In 2018, electricity-related emissions in the aluminum smelting process were 670 million tons. According to the emission reduction path, this data needs to be reduced to 8 million tons by 2050. In terms of alumina, the report predicts that the industry’s greenhouse gas emissions should fall from 171 million tons in 2018 to 90 million tons in 2050, a cut of nearly half.    At the same time, the report predicts that with economic growth, urbanization and increased infrastructure construction, the global demand for aluminum products(aluminium industrial profiles,door and window of aluminum alloy, extrusion aluminum profile,aluminum coil,etc) will increase by about 81%, which also means that the aluminum industry will bear greater pressure to reduce emissions. Marlen Bertram, Director of IAI Scenarios and Forecasts, pointed out that in order to achieve the goal of reducing carbon emissions, the aluminum industry must make major investments in technology and require commitments from all members of the value chain. He also said: “As one of the most recyclable materials on the planet, the amount of aluminum recycled may increase by about 183%. In general, according to our calculations, compared with 2050, the current aluminum industry All measures to improve recycling rate and resource efficiency can achieve the goal of reducing carbon dioxide emissions by 20%. We believe that the aluminum industry’s various actions and initiatives to reduce greenhouse gas emissions in its production process and increase recycling will make it effective It has achieved good results in tackling climate change and has become the best practicer in reducing carbon in the mining sector."At the same time, I also believe that our aluminum products (industrial aluminum profiles, doors and windows of aluminum, extruded aluminum profiles) will become better and better, with high quality and high service.
