Easy to install and move
Aluminum extruded round tubes can be made of pure aluminum or a variety of aluminum types, such as 1060, 3003, 5052, 5083, 6061, 6063, 7075, etc. Different aluminum has different mechanical properties and corrosion resistance, has good bending properties, is easy to install and move, and meets the installation needs of different application scenarios.
Reprocessing is required
Aluminium extruded round tube has a uniform circular cross-section, but the length and diameter can be customized according to customer needs. Common lengths range from 1 to 5 meters, and diameters range from 5 mm to 500 mm (or even more). Precision aluminum tubes need to be reprocessed after extrusion, such as cold drawing, fine drawing or rolling, to achieve higher precision requirements.
More energy you can save
As the connecting pipe between the indoor unit and the outdoor unit of the air conditioner, the lower the heat transfer efficiency, the more energy can be saved. In other words, the better the insulation, the more electricity is saved. Since the refrigerant does not contain moisture, the inner wall of the aluminum extruded round tube does not corrode, thus extending the service life of the product.
and its rich colors and textures
In order to improve the corrosion resistance, aesthetics and durability of aluminum extruded round tubes, a variety of surface treatments can be carried out, such as anodizing, electrophoretic coating, fluorocarbon spraying, powder coating, wood grain transfer, etc. These treatments can enhance the corrosion resistance of the material and its rich colors and textures.

Conveying pipes: Aluminum extruded round pipes are also used as conveying pipes in chemical equipment for conveying various liquid and gaseous media. Its smooth inner wall and its non-susceptibility to fouling allow it to maintain the fluidity and cleanliness of the media.
5. Furniture manufacturing
Frames & Brackets: Aluminium extruded round tubes are widely used in furniture manufacturing due to their lightweight, strong and aesthetically pleasing properties. It can be used to make the leg frame of a table, the frame of a chair, the bracket of a bookshelf and other components to improve the stability and aesthetics of furniture.
Process
1. Production line
Melting & Casting:
The raw material (ingots or alloys) is fed into a melting furnace to be heated and melted.
After refining and degassing, the molten aluminium is cast into a billet suitable for extrusion.
Extrusion:
The cast blank is fed into the extruder.
In an extruder, the blank is heated to the appropriate temperature and then extruded into a round tube shape through a die.
During the extrusion process, parameters such as temperature, pressure, and speed need to be strictly controlled to ensure the quality and performance of the product.
Cooling & Cutting:
Extruded round tubes need to be cooled to relieve internal stresses and improve dimensional stability.
After cooling, the round tube is cut to the desired length.
Surface Treatment:
Depending on the customer's needs, the round tube may need surface treatment such as anodizing, electrophoretic coating, fluorocarbon spraying, etc.
These treatments enhance the corrosion resistance of the material and give it a rich color and texture.
Quality Inspection & Packaging:
Perform quality inspection on the finished product, including inspection of size, shape, surface quality, etc.
Qualified products are packed and ready to be shipped.
2. Raw materials
High Purity:
The purity of the aluminum ingots is usually very high to ensure that the extruded round tube has good mechanical properties and corrosion resistance.
Alloying:
To meet the needs of different applications, aluminum ingots can be alloyed with other metal elements such as copper, magnesium, zinc, etc.
The alloyed aluminum alloy has higher strength, hardness and corrosion resistance.
Good machinability:
Aluminum ingots and aluminum alloys have good machinability and are easy to be extruded into products of various shapes and sizes.
Cost-effective:
Aluminum ingots and alloys are less expensive than other metal materials and are easy to recycle and reuse.
