Aluminum tube profiles is widely used worldwide today because of its high cost effectiveness and natural corrosion protection through a transparent layer of alloy called alumina. This layer can be enhanced chemically and electrochemically to provide greater protection. Aluminum tube profiles can recycled in the world. It does not lose any features during recycling and can be recycled an infinite number of times.
You may want to know, how to produce the aluminum tube profiles. Let’s talk about it for the rest of the article.

1. Principles of aluminum tube profiles extrusion process
The aluminum tube profiles extrusion process can be compared to squeezing toothpaste out of a tube. The continuous flow of toothpaste is shaped like a rounded tip, just as an aluminum tube profiles extrusion is shaped like a mold. By changing the tip or mold, different aluminum tube profiles can be formed. If you flatten the opening of the tube, a flat tube of toothpaste will appear. Aluminium can be extruded into almost any imaginable shape with the help of powerful hydraulic presses capable of exerting pressures of between 100 and 15,000 tonnes.
2. Aluminum tube profiles extrusion heating step
The aluminum billet is heated in the furnace to approximately 750 to 925 F, which is the temperature at which the aluminum becomes a soft solid.
Once the desired temperature is reached, stains or lubricants are applied to the billet and the hammer to prevent the parts from sticking together, and the billet is then transferred to a steel extruder vessel.
3. Aluminum tube profiles extrusion reshape step
The aluminum tube profiles reshape step is just after the heating step.
The hammer exerts pressure on the blank, pushing it through the container and through the mold. The soft but strong metal is extruded through the opening in the mold and away from the press.
Another billet is loaded and welded to the previous billet, then the process continues. The extruder may slowly develop complex shapes at a rate of about a foot per minute. Simpler shapes can reach speeds of up to 200 feet per minute.
When aluminum tubing the shaped section has reached the desired length, it is cut and transferred to a cooling table, where it is cooled quickly with air, spray, water bath or mist.
4. Aluminum tube profiles extrusion molding step
After cooling, the aluminum extruder is moved to a stretcher where it is straightened and machined to improve its hardness and strength and release internal stress.
At this stage, the extruder is cut to the desired length by a saw.
After cutting, the extruded aluminum tube profiles parts can be cooled at room temperature or moved to the aging furnace. In a controlled temperature environment, the heat treatment can accelerate the aging process.
After sufficient aging, the extruded aluminum tube profiles can be refined (lacquered or anodized), manufactured (cut, machined, bent, welded, assembled) or ready for direct delivery to the customer.
The aluminum tube profiles extrusion process actually enhances the properties of the aluminum tubes and results in a stronger and more flexible final product than ever before.It also forms a thin layer of alumina on the metal surface, giving it a weatherproof and attractive natural finish that requires no further treatment unless other finishes are required.
