Do you know the difference between seamless aluminum tube and welded aluminum tube? According to the shape, extrusion, thickness, performance and other different types of aluminum tube can be divided into different types of aluminum tube, the range of application is also different, and for the difference and performance of seamless aluminum tube and seam aluminum tube
First, the production process is different
Seamless aluminum tube is a kind of high strength alloy aluminum material, it is produced by the reverse extrusion technology after the aluminum rod is perforated. This production process makes there is no nuclear membrane line inside the aluminum tube, so it will not crack during high-speed rotating processing, maintaining the integrity of the product and the aesthetic appearance. Because of the uniformity of its internal structure, seamless aluminum tube has high strength and corrosion resistance, and can withstand greater external force and pressure. In addition, the inner wall of the seamless aluminum tube is smooth and not easy to accumulate dirt, which also helps it maintain good corrosion resistance. Because it is a tubular structure without welded joints, the appearance of seamless aluminum tubes is very beautiful, without obvious welding traces. However, compared with the slotted aluminum tube, the manufacturing cost of seamless aluminum tube is higher, so the price is relatively high.
Extruded aluminum tubes require the aluminum to be heated to a higher temperature and then extruded out of the mold to form a tube. In contrast, the wall thickness of extruded aluminum tube is more uniform, but in the manufacturing process, the surface of aluminum tube is prone to wrinkles and oxides, which need to be solved by surface treatment. Extruded aluminum tube is an aluminum alloy tube made by extrusion process, also known as extruded aluminum profile. In the extrusion process, the aluminum alloy material is first heated to a certain temperature, and then through the pressure of the extrusion machine, after the extrusion deformation of the special mold, the final molding. Extruded aluminum tube has the following characteristics:
1. High production efficiency, can be mass-produced, widely used.
2. High surface finish and beautiful appearance.
3. The shape of the section is diversified and can be customized according to needs
Two, the surface treatment is different
Due to the difference of manufacturing process, the surface treatment method of seamless aluminum tube and extruded aluminum tube is also different.
The surface treatment of seamless aluminum tube generally adopts pickling, sandblasting, polishing and other ways to effectively remove the oxide and impure substances on the surface of aluminum tube, increase its surface smoothness, and improve the anti-corrosion performance.
In contrast, the surface treatment of extruded aluminum tubes requires more processes, and the commonly used surface treatment methods are anodizing, sandblasting, thermal transfer printing and so on. But even after surface treatment, there are still some wrinkles and traces on the surface of the extruded aluminum tube.
Third, different application fields
Due to the different manufacturing process and surface treatment, the application fields of seamless aluminum tube and extruded aluminum tube are also different.
Seamless aluminum tube is widely used in chemical, petroleum, aviation, aerospace and other fields, especially suitable for high pressure, high temperature conditions of the use of the environment. Extruded aluminum pipe is mainly used in household, construction, electrical appliances and other fields, can also be used in vehicles, ships and other structural parts.
In short, there are some differences between seamless aluminum tube and extruded aluminum tube in terms of manufacturing process, surface treatment and application field. Choosing the right type of aluminum tube according to different use environments can effectively improve the service life and performance of products.
With the rapid development of automobile industry, the application prospect of aluminum tube in automobile manufacturing is more and more broad. Aluminum tubes have the advantages of light weight, high strength, and corrosion resistance, so they are widely used in key components such as braking systems, cooling systems, and air conditioning systems in automobile manufacturing.
In terms of technological innovation, the manufacturing process and material technology of aluminum tube are constantly innovated. For example, the adoption of new alloy materials and manufacturing processes can improve the strength and corrosion resistance of aluminum tubes, further improving their application performance in automobile manufacturing. In addition, by optimizing the design and process control, the cost of aluminum tube can be further reduced and its competitiveness can be improved.
Aluminum tube has a broad application prospect in automobile manufacturing and has an important space for technological innovation. With the development of the automotive industry, aluminum tubes will be more widely used in key components such as braking systems, cooling systems and air conditioning systems, while continuously improving their performance and reducing costs through technological innovation, which will further promote the development of the automotive industry.
