1 Cold-drawn fine-drawn precision aluminum tube: The raw material is extruded aluminum tube and rolled aluminum tube. The aluminum tube processed by this processing method: high precision, smooth inner and outer surfaces, and the best of the three mechanical properties. Therefore, it is widely used in various industries, such as luggage trolley, film and television tripod, heating plate of electric heating equipment.

In modern industry, many products must use cold-drawn precision drawn precision aluminum tubes, such as oil pipelines for automobiles, aerospace, laser fax, photosensitive drums in printers, aluminum tubes for magnetic rollers, etc. For precision turned parts, To reduce the turning allowance and increase the yield rate, cold-drawn aluminum tubes are also attracting attention and use.

2 Welded pipe: There are strict requirements on the thickness of aluminum plates and aluminum coils, and the pattern requirements are fine. It is a relatively small or thin aluminum tube. It is generally used in small objects such as pen tubes and jewelry holders.
