What is aluminum profile?

Aluminum is a silvery white gold. In humid air, aluminum can form an oxide film that prevents metal corrosion, with a relative density of 2.7g/cm3, a melting point of 660°C, a boiling point of 2327°C, high specific strength, good electrical and thermal conductivity, high reflectivity and Oxidation resistance.

Therefore, aluminum is an excellent match for the finished material. These aluminum parts, including windows and radiator fins, are called aluminum profiles.

Aluminum profiles are aluminum tube materials with different cross-sectional shapes obtained by hot melting and extrusion of aluminium rods. The forming process of aluminum profiles mainly includes five processes: casting, extrusion, cutting, CNC washing and cutting, surface pretreatment, and coloring.

What are the types of aluminum profiles?

Aluminum profiles can be processed from any type of aluminum, and 1-series aluminum to 7-series aluminum can be processed as raw materials for aluminium profiles. Therefore, they also correspond to the aluminum profiles of different license plates.

We usually use “grades” to refer to different types of aluminum profile products. The first digit in the “grade” indicates the aluminium alloy series, the second digit indicates the modification of the original aluminum alloy, and the last two digits indicate the purity of the aluminum alloy in the same group.

• 4A01 Aluminum: It has high silicon content, heat resistance, and wear resistance. It is used in construction materials, machine parts, forging materials, welding materials, and other fields.
• 5052 aluminum: It is the most representative product of medium-strength alloys. It has good corrosion resistance, weldability, and formability, especially high fatigue strength and good seawater resistance. Therefore, it is used in the manufacture of aircraft fuel tanks, oil pipes, sheet metal parts for vehicles and ships, instruments, street lamp brackets and rivets, hardware products, and other products.
• 6061 Aluminum: It is a heat-treated alloy, 6061 alloy has extremely high corrosion resistance. Therefore, it is suitable for the production of screws, ships, vehicles, and other products.
• 6N01 aluminum: It is a medium-strength extrusion alloy, which can be used for large-scale thin meat profiles with complex shapes, with good corrosion resistance and weldability. Suitable for vehicles, land structures, and ships.
• 6063 aluminum: a representative alloy for extrusion, its strength is lower than that of 6061, and its extrudability is good. It can be used as a profile with complex cross-sectional shapes. It has good corrosion resistance and surface treatment. It is suitable for building highway guardrails, vehicles, and furniture, home appliances, decorations.
• 7072 aluminum: low electrode potential, mainly used for anti-corrosion covering leather, also suitable for heat exchanger fins, air conditioner aluminum foil, and ultra-thin strips.
• 7075 aluminum: one of the alloys with the highest strength in aluminium alloy, but the corrosion resistance is not good. Suitable for aircraft, ski poles, and thick plate forgings.

The main applications of aluminum profiles:

1. Architectural aluminum profiles (doors, windows, curtain walls).
2. Radiator aluminium profile.
3. General industrial aluminum profiles: mainly used in industrial manufacturing, such as automated machinery and equipment, skeletons, etc., can be customized by mold opening.
4. Aluminim alloy profiles for rail vehicle structure: mainly used in the manufacture of rail vehicle bodies.
5. Decorate aluminum profiles, make aluminum alloy face frames, and mount various decorative paintings.
6. Appearance aluminum profiles are mainly used in home appliances or communication industries, such as mobile hard disks, mobile power supplies, TV sets, monitors, and other internal structures and external decoration.

The aluminum extrusion (also known by ‘aluminum frames’) forming process is a bulk plastic deformation process. First, a billet of aluminum is preheated to a specified temperature that is still comfortably below the material melting point in order to facilitate the plastic flow of the material.

The heated billet is then forced through a tooling die that is designed to shape and form the billet into the corresponding profile cross section. This industrial extrusion process is analogous to the culinary technique used to make different types of pasta; and also a technique seen to form shapes in the children’s toy, Play-Doh.

Advantages of Aluminum Extrusion

Aluminum is a very commonly specified material for use in extrusions and shape profiles because it possesses mechanical characteristics that make it ideally suited for the shaping and forming metal from billet sections.  The high malleability of aluminum means that the metal can be readily shaped into a variety of sections without expending significant energy on the tooling or forming process, and the melting point of aluminum is also generally on the order of half that of ordinary steel.

Both of these facts mean that the aluminum extrusion process has a relatively low energy footprint translating into low tooling and manufacturing costs. Finally, aluminum also possesses a high strength to weight ratio, making it an excellent choice for industrial applications.

Types of Profiles

A wide variety of intricate aluminum extrusion profile types can be created at varying thicknesses. These profiles can feature a wide variety of intricate void spaces, as necessitated by the end use application.  A wide range of internal voids are available in order to facilitate a wide variety of automation applications and also satisfy any performance weight requirements.

The most common type of aluminum profile is the hollow beam profile which is simply a variation of the square profile. There are also other profile types such as the triangular, single radius, and L-shaped profile.

Surface Types:

As a byproduct of the extrusion process, there are sometimes small, barely visible lines present on the surfaces of the profiles. This is a result of the extrusion tooling, and additional surface treatments can be specified to remove these lines. There are a few of secondary surface processing operations that can be performed such as face milling after the main extrusion forming process in order to improve the surface finish of the profile section.

These processing operations can be specified in order to improve the geometry of the surface to improve the part profile by reducing the overall surface roughness of the extruded profile. These treatments are typically specified in applications that require precise positioning of the parts or where mating surfaces must be controlled tightly.  Surface treatments can also add additional corrosion resistance, improve the hardness of the profile, or even add electrical insulation to the extrusions.

Uses of Profiles Sections:

Aluminum profiles are most commonly used across industrial automation applications such as automated motion applications on process lines and industries throughout manufacturing. They are strong and yet light enough that they yet can be easily man-handled and built into various configurations as necessitated by the automation structure.

Outside of the traditional automation applications, structural-grade aluminum extrusions are even being specified as part of weight reduction efforts. In this sense, they are increasingly being employed as frames in other end-use consumer products, such as automobiles and LEED building projects. As more advanced aluminum alloys and surface coating techniques are developed, the uses are expanding into these new areas.

Conclusion

In closing, extrusion aluminum sections are versatile and ideal for use in building automation applications, and aluminum is an excellent structural material, which lends itself perfectly for use in profile extrusions. More likely than not, there is an aluminum profile that’s perfectly tailored to the specific automation application.
