Comprehensive knowledge of aluminum alloy profiles:
Aluminium profiles are aluminum materials with different cross-section shapes through hot melt and extrusion.The production process of aluminum profiles mainly consists of three processes: melting, extrusion and coloring (including: oxidation, electrophoretic coating, fluorine spraying, powder spraying, etc.).
![[Image: online-shopping-280x124.jpg]](http://hmaluprofile.net/content-images/online-shopping-280x124.jpg)
The aluminum profiles are divided into:
1. Industrial aluminum profile: mainly used for airplanes, trains, industrial radiators, automobiles, electrical appliances, etc.
2. Aluminum alloy building profile: mainly used for building doors and Windows, curtain walls, indoor and outdoor decoration and architectural structure.
The aluminum profiles are divided into:
1. Anodized aluminum: the surface of the profile is oxidized by anodic oxidation, electrolytic coloring or organic coloring.
2. Electrophoresis coating aluminum: the surface of the profile is combined with anodic oxidation and electrophoresis.
3. Powder spraying aluminum: the surface of the profile is coated with thermosetting organic polymer powder.
4. Fluorocarbon paint spraying aluminum: the profile surface is coated with polyvinylidene fluoride paint.At present, the commonly used heat insulation profile is a kind of aluminum profile which adopts a strip or pouring compound.
Key indicators:
1. Appearance quality: the surface of anodized profile does not allow for the defects such as electric burn and peeling of oxide film;Electrophoresis, powder, fluorine carbon profile after the paint film should be uniform, clean, smooth, there is no wrinkle, crack, bubble, flow mark, inclusion and peeling paint film effects such as the use of defects, but within the scope of the profile end 80 mm allows local without membrane.The appearance quality of the aluminum alloy building profile affects the architectural decoration effect, so the surface of the factory profile must be coated to avoid surface scratch, collision and corrosion in the process of transportation and stacking.In the market, some aluminum alloy profiles have similar patterns of water striation and mildew, which reflect the defects of the production process.
2. Wall thickness: the wall thickness of the profile is one of the main factors affecting the strength of the workpiece. The main profile is the stressed part in the project.For example, the minimum nominal wall thickness of the outer window main profile shall not be less than 1.4mm.
3. Film thickness: extruded aluminum alloy profiles, whose surface corrosion resistance is not strong, the surface treatment should be carried out to increase the corrosion resistance, wear resistance and appearance aesthetics of aluminum.The film thickness of anodized aluminum material is divided into AA10, AA15, AA20, AA25, and the thickness of the electrophoretic coating aluminum film is divided into A.B.S, powder spraying aluminum decorative coating on the surface of the minimum local thickness of 40 or higher um, fluorocarbon spraying aluminum decorative paint on the surface of the layer thickness for coating of different kinds have different requirements, the second with the average film thickness acuity 30 um, three with the average film thickness 40 um, four or more with the average film thickness acuity 65 um.
4. Chemical composition and mechanical properties: the technical parameters of chemical composition and mechanical properties of aluminum alloy profiles are different, and the customer should check them one by one according to the standard (contract).
5. Color and color difference: there are differences in color and color difference between different brands and supply states.It is suggested that the influence of color and color difference on architectural structure should be taken into consideration when the alloy plate number and supply status are selected.
6. Anti-salt spray corrosion, abrasion, waiting and mortar, etc. : this is an important technical parameter of aluminum alloy profile, which reflects the properties of aluminum alloy profiles and influences the use.
All the above contents are arranged according to the problems encountered in the actual work of the students. For reference, please timely communicate and correct any questions.

| What Aluminum Extrusion Process |
|

Extrusion Defined
Extrusion is described as the system of shaping material, such as aluminum, via forcing it to drift through a formed opening in a die. Extruded fabric emerges as an elongated piece with an equal profile as the die opening.
To resource in appreciation the aluminum extrusion technique suppose about a Play-Doh® Fun Factory and how it works. Think of the Fun Factory as the extrusion press, the take care of like the ram, the structure bar as the die, and the Play-Doh® as the aluminum billet. The first step is to select the preferred shape and color. Think of the form as the die and the shade as the temper and alloy needed. Next, the Play-Doh® is inserted into the holding chamber and strain is applied to the handle, which forces Play-Doh® via the shape. In an extrusion press, stress is applied to the billet by the ram the place the dummy block is connected to the top of the ram stem. When Play-Doh® starts offevolved to emerge, it has effectively been "extruded". The equal principles observe to extrusions from aluminum billets however appreciably more distinctive and state-of-the-art technologies are involved.
Press dimension determines how giant of extrusion can be produced. Extrusion measurement is measured with the aid of its longest cross-sectional dimension, i.e. its fit inside a circumscribing circle. A circumscribed circle is the smallest circle that will totally enclose the pass area of an extruded shape.
The most necessary element to understand in the extrusion system is temperature. Temperature is most vital due to the fact it gives aluminum its desired traits such as hardness and finishes.
Steps in the aluminum extrusion process
1. Billets need to be heated to about 800-925° F.
2. After a billet reaches the favored temperature, it is transferred to the loader where a skinny film of smut or lubricant is added to the billet and to the ram. The smut acts as a parting agent (lubricant) which maintains the two parts from sticking together.
3. The billet is transferred to the cradle.
4. The ram applies strain to the dummy block which, in turn, pushes the billet until it is inner the container.
5. Under strain the billet is overwhelmed against the die, turning into shorter and wider until it has full contact with the container walls. While the aluminum is pushed through the die, liquid nitrogen flows around some sections of the die to cool it. This will increase the lifestyles of the die and creates an inert ecosystem which continues oxides from forming on the structure being extruded. In some cases, nitrogen fuel is used in the area of liquid nitrogen. Nitrogen fuel does now not cool the die however does create an inert atmosphere.
6. As an end result of the stress delivered to the billet, the tender but solid metallic begins to squeeze thru the die opening.
7. As an extrusion exits the press, the temperature is taken with a True Temperature Technology (3T) instrument hooked up on the press platen. The 3T archives exit temperature of the aluminum extrusion. The most important cause of understanding the temperature is to keep most press speeds. The goal exit temperature for extrusion is established upon the alloy. For example, the goal exit temperature for the alloys 6063, 6463, 6063A, and 6101 is 930° F (minimum). The goal exit temperature for the alloys 6005A and 6061 is 950° F (minimum).
8. Extrusions are pushed out of the die to the leadout table and the puller, which publications metal down the run-out table at some stage in extrusion. While being pulled, the extrusion is cooled through a collection of followers along the complete size of the run-out and cooling table. (Note: Alloy 6061 is water quenched as nicely as air quenched.)
9. Not all of the billet can be used. The remainder (butt) carries oxides from the billet skin. The butt is sheared off and discarded while another billet is loaded and welded to a formerly loaded billet and the extrusion system continues.
10. When the extrusion reaches a favored length, the extrusion is reduced with a profile noticed or a shear.
11. Metal is transferred (via a belt or walking beams systems) from the run-out table to the cooling table.
12. After the aluminum has cooled and moved along the cooling table, it is then moved to the stretcher. Stretching straightens the extrusions and performs 'work hardening' (molecular re-alignment which gives aluminum multiplied hardness and extended strength).
13. The subsequent step is sawing. After extrusions have been stretched they are transferred to a noticed table and reduce to particular lengths. The cutting tolerance on saws is 1/8 inch or greater, depending on saw length.
After the components have been cut, they are loaded on a transportation device and moved into age ovens. Heat-treating or artificial growing old hardens the metal through speeding the getting old process in a managed temperature surroundings for a set quantity of time.

Aluminum alloys are divided into two major categories: wrought and casting alloys. A further differentiation for each category is based primary on mechanism of property development. Many Aluminum alloys respond to thermal treatment based on phase solubility. These treatments include solution heat treatment, quenching and precipitation, or age hardening.
[img=300x0]http://www.aluminiumstrip-hm.com/wp-content/uploads/2017/08/aluminum_foil_11-300x168.jpg[/img]
In order to improve surface properties of final products, such as wear resistance, corrosion resistance, reflectivity etc., different types of surface treatment were designed. All of them are divided into several groups, such as electrochemical treatments, chemical treatments and coatings. In this article their terms and definitions will be explained.
Electrochemical treatment
Electrochemical brightening: Electrochemical treatment to improve the optical reflectivity of a surface.
Electropolishing: Polishing of a metal surface by making it anodic in an appropriate electrolyte.
Anodized metal Metal with an anodic coating, produced by an electrolytic oxidation process in which the metal is converted to a mainly oxide coating having protective, decorative or functional properties.
Clear anodized metal: Metal with a substantially colorless, translucent anodic oxidation coating.
Color anodized metal: Anodized metal colored either during anodizing or by subsequent coloring processes.
Integral color anodized metal: Metal that has been anodized using an appropriate (usually organic acid based) electrolyte which produces a colored coating during the anodizing process itself.
Electrolytically colored anodized metal: Metal with an anodic oxidation coating that has been colored by the electrolytic deposition of a metal or metal oxide into the pore structure.
Dyed anodized metal: Metal with an anodic oxidation coating colored by absorption of dye-stuff or pigments into the pore structure.
Combination color anodized metal: Metal with an anodic oxidation coating that is colored by electrolytic coloring or produced by integral color anodizing followed by absorption dyeing.
Interference color anodized metal: Metal with an anodic oxidation coating colored by means of optical interference effects.
Bright anodized metal: Anodized metal with a high specular reflectance as the primary characteristic.
Protective anodizing: Anodizing where protection against corrosion or wear is the primary characteristic and appearance is secondary or of no importance.
Decorative anodizing: Anodizing where a decorative finish with a uniform or a esthetically pleasing appearance is the primary characteristic.
Architectural anodizing: Anodizing to produce an architectural finish to be used in permanent, exterior and static situations where both appearance and long life are important.
Hard anodized metal: Anodized metal on which the anodic oxidation coating has been produced with wear and/or abrasion resistance as the primary characteristic.
Sealing: Treatment of anodic oxidation coatings on metal to reduce porosity and the absorption capacity of the coating by hydrothermal processes carried out after anodizing.
Cold impregnation: Treatment of anodic oxidation coatings on metal to plug the pores and reduce the absorption capacity of the coating by chemical processes carried out at low temperatures after anodizing.
Significant surface: The part of the product covered or to be covered by the coating and for which the coating is essential for serviceability and/or appearance.
Chemical treatment
Chemical brightening: Chemical treatment to improve the optical reflectivity of a surface.
Chemical polishing: Polishing of a metal surface by immersion in a solution of chemical reagents.
Degreasing: Removal of oil or grease, usually by a suitable organic solvent or an aqueous detergent.
Etching: Roughening of the surface of a metal by overall or selective dissolution in acid or caustic media.
Pickling: Removal of a thin surface layer of a metal by chemical action, mainly by treatment in a caustic solution.
Coating
Coating (organic): Method in which a coating material is applied on a metallic substrate. This process includes cleaning and chemical pre-treatment and either:
one-side or two-side, single or multiple application of liquid or powder coating materials which are subsequently cured or
laminating with plastic films.
Coil coating: Continuous coating of a metal strip.
Backing coat: Single coating of any type with no particular requirements for appearance, malleability, corrosion protection, etc. usually on the reverse side of the coated product.
Chemical conversion coating: Treatment of a metal with chemical solutions by dipping or spraying to build up an oxide film containing chromates or phosphates.
Priming: Application of a priming paint often pigmented with a corrosion inhibitor such as zinc chromate, after suitable pretreatment.
Pretreatment priming: Application of a solution containing a resin, a chromate and an acid, which is allowed to dry on and provide the key for subsequent painting.
Single coat system: Single coating either with requirements on appearance, malleability, corrosion protection, subsequent painting, etc., or as a primer with special properties regarding adhesion and corrosion protection for post-painting applications.
Multiple coat system: System comprising a primer or a base coat, possibly intermediate coat(s), and a top coat with particular requirements on appearance, malleability, corrosion protection, etc.
Organic coating: Dry paint film of the coated product or the organic film metal laminate.
Film coating: Organic film applied to a substrate to which an adhesive and, if appropriate, a primer has been applied beforehand.
Lacquering: Coating with a formulation based on a dissolved material which forms a transparent layer primarily after drying by evaporation of the solvent.
