Recently, the prices of precious metals such as aluminum and copper in the United States have risen sharply. This change has stirred up waves in the global market like ripples, and has also brought a rare dividend period to the Chinese aluminum and copper market. Aluminum, as a basic raw material that occupies an important position in the national economy, is widely used in many fields due to its excellent characteristics such as light weight, strong texture, good conductivity and strong thermal conductivity. Aluminum plates, aluminum tubes and aluminum coils, as important branches of aluminum products, have also attracted much attention in this aluminum and copper market boom. Next, let us take a deeper look at these three types of products.
Aluminum tube: light, corrosion-resistant, and versatile
Aluminum Pipes is a type of non-ferrous metal tube. It is a metal tubular material made of pure aluminum or aluminum alloy through extrusion and is hollow along its entire longitudinal length. It can have one or more closed through holes, and the wall thickness and cross-section are uniform and consistent. It is usually delivered in a straight line or in a roll.
There are many ways to classify aluminum tubes. According to the shape, it can be divided into square tubes, round tubes, patterned tubes, and special-shaped tubes; according to the extrusion method, there are seamless aluminum tubes and ordinary extruded tubes; according to the precision, it is divided into ordinary aluminum tubes and precision aluminum tubes; according to the thickness, there are ordinary aluminum tubes and thin-walled aluminum tubes. Aluminum tubes are corrosion-resistant and light in weight, and have excellent bending properties and are easy to install and move.
In practical applications, aluminum tubes are widely used in automobiles, ships, aerospace, aviation, electrical appliances, agriculture, electromechanical, home furnishing and other industries. For example, in the automotive and aviation fields, aluminum tubes are used to manufacture various pipes and structural parts due to their light weight and high strength. In the air conditioning industry, aluminum tubes play an important role as connecting tubes, and have significant advantages in welding technology, service life and energy saving.
Aluminum plate: diverse functions and wide application
Aluminum Sheets is a plate-shaped aluminum product made by a series of processes such as rolling and extrusion of aluminum ingots through plastic processing methods. In order to ensure the final performance of the plate, the finished product needs to be processed by annealing, solid solution treatment and other processes.
From the classification point of view, aluminum plates are divided into detailed categories according to alloy element content, processing technology, thickness and surface shape. According to the content of alloy elements, it can be divided into several series, such as 1××× series industrial pure aluminum plate, 2××× series aluminum-copper alloy aluminum plate, etc. The 1××× series aluminum plate has a very high aluminum content, with a purity of more than 99.00%. The production process is relatively simple and the price is affordable. It is widely used in conventional industries. For example, 1050 aluminum plate is often used in the production of daily necessities, heat sinks and other products; 2××× series aluminum plates have higher hardness and a copper content of about 3-5%. They are mostly used in the aerospace field. For example, 2024 aluminum plates are often used in the manufacture of aircraft structural parts.
According to the processing technology, aluminum plates can be divided into cold-rolled aluminum plates and hot-rolled aluminum plates; according to thickness, they can be divided into thin plates and medium-thick plates; according to surface shape, they can also be divided into flat plates and patterned aluminum plates. In practical applications, aluminum plates can be seen everywhere, from lighting fixtures, solar reflectors, to building exteriors, interior decoration, to aerospace and military fields, aluminum plates play an indispensable role.
Aluminum coil: an important material for industrial applications
Aluminum Coil is a metal product used for flying shearing after rolling and bending by a casting mill. Aluminum coils are widely used in electronics, packaging, construction, machinery and other industries.
According to the different metal elements contained, aluminum coils can be divided into 9 series. The 1000 series aluminum coils have a high aluminum content and are affordable, and are widely used in conventional industries; the 2000 series aluminum coils have a high hardness and are mostly used in the aviation field; the 3000 series aluminum coils have good anti-rust performance and are often used in humid environments such as air conditioners and refrigerators; the 5000 series aluminum coils are aluminum-magnesium alloys with low density and high tensile strength, and are used in both aviation and conventional industries.
When processing aluminum coils, since silicon has a corrosive effect on cemented carbide, it is necessary to select appropriate tools according to the silicon content. When the silicon content exceeds 8%, it is recommended to use diamond tools; when the silicon content is between 8% and 12%, both ordinary cemented carbide tools and diamond tools can be used, but when using cemented carbide tools, tools that have been processed by the PVD method, do not contain aluminum elements, and have a smaller film thickness must be used.
Against the current background of a sharp rise in aluminum and copper prices in the United States and a bonus period for the Chinese aluminum and copper market, the aluminum plate, aluminum tube, and aluminum coil industries have also ushered in new development opportunities. On the one hand, the price increase has brought more profit space for enterprises; on the other hand, with the continuous advancement of science and technology and the continuous development of various industries, the demand for aluminum plates, aluminum tubes, and aluminum coils is also increasing, especially in emerging fields such as new energy and aerospace.
However, we should also be aware that market fluctuations and uncertainties still exist. Aluminum prices are affected by many factors, such as the global economic situation, policies and regulations, and supply and demand. In the future development, enterprises in the aluminum plate, aluminum tube and aluminum coil industries need to continuously improve their technical level and innovation ability, optimize product structure and improve product quality to better adapt to market changes and occupy a place in the fierce market competition. At the same time, enterprises also need to pay attention to industry dynamics, strengthen risk management and reasonably respond to the challenges brought by market changes.
