Aluminum tubes are mainly classified into the following types:
By shape: square tubes, round tubes, patterned tubes, special‑shaped tubes, and global aluminum tubes.
According to the extrusion method: seamless aluminum tubes and conventional extruded tubes.
Classified by precision: ordinary aluminum tubes and precision aluminum tubes; the latter typically undergo secondary processes such as cold drawing and rolling after extrusion.
By thickness: standard aluminum tubing and thin-walled aluminum tubing.
Performance: Corrosion-resistant and lightweight.
Features
It is a high‑strength duralumin that can be strengthened through heat treatment. In the annealed, quenched, and hot‑worked conditions, it exhibits moderate ductility and good spot‑weldability. When welded by gas welding or argon arc welding, aluminum tubing is prone to intergranular cracking; after quenching and cold work hardening, its machinability improves, whereas in the annealed condition it is relatively poor. Its corrosion resistance is low, typically enhanced by anodizing, painting, or applying an aluminum coating. Additionally, it can be used as a mold material.
One of the key advantages of aluminum tubing lies in its welding technology: this technique is well-suited for the industrial production of thin-walled copper–aluminum tubes, a task that has long been regarded as a world-class challenge and represents the critical technology enabling the substitution of copper with aluminum in air-conditioning service lines.
Secondly, there is an advantage in service life: since the refrigerant contains no moisture, the inner walls of the aluminum tubing do not corrode, and consequently, the inner walls of the copper–aluminum connecting pipes remain free from corrosion as well.
Third, energy-saving advantages: the lower the heat transfer efficiency of the piping connecting the indoor and outdoor units of an air conditioner, the greater the energy savings; in other words, the better the insulation performance, the more electricity is saved.
Fourth, it exhibits excellent flexural performance and is easy to install and handle.

Let us introduce you to what aluminum tubing is.
Aluminum tubing typically refers to pipes made from aluminum alloys. Aluminum alloys are materials composed of aluminum combined with other metallic elements, characterized by their light weight, high strength, and excellent corrosion resistance, making them widely used across various industries.
Aluminum tubes are mainly classified into the following types.
Classified by precision: ordinary aluminum tubes and precision aluminum tubes; the latter typically undergo secondary processes such as cold drawing and rolling after extrusion.
With the rapid growth of the new‑energy vehicle industry, automotive thermal management systems are confronting entirely new challenges and opportunities. In this field, aluminum tubing, thanks to its superior performance and broad range of applications, has steadily emerged as an unsung leader in thermal management for new‑energy vehicles, providing robust support for enhanced vehicle performance and safe operation.
Production and Manufacturing of Aluminum Tubes
Aluminum tubes are classified into four main types based on their forming process: hot-extruded aluminum tubes (the mainstream), cold-drawn and precision-rolled aluminum tubes, welded aluminum tubes, and impact-extruded pharmaceutical aluminum tubes. Among these, the most widely used in the industry is seamless or split‑die extruded aluminum tubing.
What is the difference between 409 stainless steel and 430 stainless steel?
Compared with ordinary low‑carbon steel, 409 stainless steel sheet exhibits poorer thermal conductivity and lower elongation; consequently, greater deformation forces are required during shearing and bending. For 321 stainless steel sheet, springback during bending is more pronounced than in carbon steel. Moreover, since the elongation of stainless steel sheet is lower than that of carbon steel, the bend radius R of the workpiece should be larger than that for carbon steel during bending operations; otherwise, cracking is likely to occur.
What is the difference between 202 stainless steel and 304 stainless steel?
202 stainless steel and 304 stainless steel are both austenitic stainless steels at their core, non-magnetic, and visually quite similar. However, the key difference lies in their nickel content, which results in significant variations in their mechanical properties and price.
