Generally we buy aluminum tubes are based on the name of it has the manufacturing process, such because cold drawn aluminum tubes and extruded aluminum tubes. On the other hand, what is the difference in their craftsmanship, and which practice caused the difference, remains a mystery to a lot of people. If you're interested, take a look at this article.

How To Produce Extruded Aluminum Tube?
Aluminum tube extrusion molding would be to put a strong pressure about the metal blank placed inside the mold cavity,,which forces the metal blank to produce directional plastic deformation and extrudes it from your die hole of the extrusion die to be able to obtain the required segment shape, size and pieces or semi-finished extruded aluminum tubes with certain mechanical properties.
The extruded metal can obtain a more intense and homogeneous three-way compression stress state from the deformation zone than your rolling forging, which can grant full play to the plasticity with the processed metal itself.
Extrusion molding are not able to only produce bars, tubes, moulds and wires with simple mix section shapes, but additionally produce profiles and aluminum tubes with complex combination section shapes.
Your flexibility of extrusion molding, just needs to replace the mold and various extrusion tools, you could produce aluminum tubes regarding different shapes, specifications and also varieties on one gear, the operation of upgrading the extrusion mold is definitely simple and quick, time saving, efficient.
High precision extruded aluminum tubes have good surface quality. It also improves the utilization rate and the provide of metal materials. The extrusion process is known for a good impact on your mechanical properties of light weight aluminum tubes.
Small technological process, convenient development, one extrusion can or can be than hot die forging or forming rolling means of the overall structure belonging to the larger area, less machines investment, low mold expenditures, high economic benefits.
Aluminum alloy has great extrusion characteristics, especially made for extrusion processing, can be processed through a range of extrusion processes and a good deal of die structures to attain aluminum tube products.
Easy methods to Produce Cold Drawn Light weight aluminum Tube?
Cold drawn aluminum tube describes the production process associated with simultaneously applying longitudinal anxiety and transverse pressure around the material, so as upskill the strength of light weight aluminum tube. In general, cold drawing processing will be carried out in a special cold drawing machine.
While in the cold drawing process, the aluminum tube is simultaneously subjected to tension and extrusion plus plastic deformation occurs. Your cold drawn aluminum tv cross-sectional area is lowered, resulting in cold hardening. The tensile strength could be increased by 40 ~ 90%, but the plasticity is reduced plenty.
For smaller and better-quality seamless tubes, cold rolling, cold drawing or combining the two must end up being used. Cold rolling is often carried out on a two-high mill and also the tube is rolled throughout an annular pass formed by a circular groove with a variable section and a fixed tapered head.
Extruded Metal Tube vs Cold Drawn Aluminum Tube
In conditions of installation and employ, there is no difference between each, just different material consequences.
Extruded aluminum tube provides high cost, good ductility, excellent oxidation resistance, good bell-mouth pressure resistance, not easy to leak refrigerant, the drawback is high cost, using a long time can age and harden.
Extrusion molding are not able to only produce aluminum tubes by using simple cross section contour, but also produce reliable and hollow aluminum tubes together with very complex cross area shape. The cross sections regarding products change in stages over the direction of length and also gradually, and many advisors cannot be formed through other plastic processing techniques. It also ranges in dimensions, from very large ones having a diameter of 500-1000mm on the external circle of section to microscopic precision ones with a section size like a matchstick.
Cold drawn aluminum tube is the biggest advantage of inexpensive, and good bending, twisting than extruded aluminum television. Pipes often need being bent when installing air conditioning conditioners. But the shortcomings involving cold drawn aluminum tube will not be to do flared, bad pressure resistance, oxidation weight, it is easy in order to leak, if not covered insulation cotton, it is really a hidden danger.
