Why Aluminum?
There are many reasons to choose aluminum as the material for extruded profiles. Here we only share a few of them.
Aluminum stands as the material of choice for extruded profiles due to a unique combination of properties that make it exceptionally suited for a wide range of applications.
The lightweight nature of aluminum allows for ease of handling and transportation, making it an ideal choice for industries requiring materials with high strength-to-weight ratios.
Additionally, aluminum exhibits excellent corrosion resistance, ensuring durability and longevity in various environments.
Its malleability and ductility make it highly conducive to the extrusion process, allowing for the creation of intricate and precisely shaped profiles.
Furthermore, aluminum boasts superb thermal conductivity, making it suitable for applications in which heat dissipation is crucial.
The material's recyclability aligns with contemporary sustainability goals, appealing to environmentally conscious industries.
Whether in construction, automotive, or industrial machinery, the versatility, strength, and adaptability of aluminum make it the preferred material for extruded profiles, offering a perfect balance of performance, efficiency, and environmental responsibility.

Online shopThe Extrusion Process
Aluminum extrusion is a manufacturing process that transforms aluminum alloys into long, uniform profiles with cross-sectional shapes that match specific design requirements.
The process involves pushing the aluminum through a custom-shaped die, resulting in profiles that range from simple and straight to intricate and complex.
Here are the key steps involved in aluminum profile extrusion:
1. Billet Preparation: The process begins with the preparation of aluminum billets, which are cylindrical logs of aluminum alloy. These billets are typically heated to a specific temperature to make them more malleable for extrusion.
2. Container Heating: The extrusion press container, also known as the "container" or "billet holder," is preheated. This preheating helps in reducing the force required for extrusion and ensures a smoother process.
3. Die Heating: The extrusion die, a specially designed tool that shapes the aluminum, is also heated. The die is often made of tool steel and must withstand high temperatures and pressures during the extrusion process.
4. Billet Loading: The heated aluminum billet is loaded into the container of the extrusion press. The press is designed to exert tremendous pressure on the billet to force it through the extrusion die.
5. Extrusion Process: The press applies pressure to the billet, forcing it through the shaped opening of the extrusion die. As the aluminum passes through the die, it takes on the desired profile, forming a continuous length of the extruded shape.
6. Cooling: The extruded aluminum profile is then rapidly cooled using air or water quenching methods. This step is crucial for setting the shape and ensuring the structural integrity of the extruded profile.
7. Stretching and Straightening: Some profiles may undergo a stretching process to align the aluminum molecules and reduce any internal stresses. Straightening is also performed to ensure the extruded profiles meet the specified tolerances.
8. Cutting to Length: The continuous length of extruded aluminum is cut into individual profiles of the desired lengths. Precision cutting ensures uniformity and facilitates further processing.
9. Surface Treatment and Finishing (Optional): Depending on the application and design specifications, extruded profiles may undergo surface treatments such as anodizing, painting, or powder coating to enhance their appearance, corrosion resistance, and durability.
10. Quality Control: The final step involves rigorous quality control measures. This may include inspections for dimensional accuracy, surface finish, and overall compliance with specifications to ensure the extruded profiles meet the required standards.
The precise control over the extrusion process makes aluminum extrusion a preferred choice in industries that demand high-quality and precisely shaped components.

Aluminum profiles are aluminum materials with different cross-sectional shapes through hot melting and extrusion of aluminum rods. The production process of aluminum profiles mainly includes three processes: casting, extrusion, and coloring. Coloring mainly includes electrophoretic coating, oxidation, fluorocarbon spraying, powder spraying, wood grain transfer and other processes. The most common aluminum profile products are Aluminium Channel, T Slot Aluminium Extrusion, -T5 Aluminium Heat Sink, and -T5 Aluminium Association I Beam. This article will introduce in detail the classification and use of aluminum profiles.
1. Architectural aluminum profiles (divided into windows, doors, and curtain walls).
2. Radiator aluminum profiles.
3. General industrial aluminum profiles: mainly used in industrial production and manufacturing, such as automated machinery and equipment, shell skeletons, each company customizes molds according to their mechanical equipment requirements, such as assembly line conveyor belts, glue dispensers, testing equipment, elevators, shelves, etc. For the electromechanical industry and clean rooms.
4. Aluminum alloy profile for rail vehicle structure: mainly used to manufacture the rail vehicle body.
5. Mounting aluminum profiles to make aluminum alloy picture frames, mounting various exhibition and decorative paintings.
It can be divided into alloy grade aluminum profiles such as , , , , , , among which six series are the most common. The difference between different grades lies in the different proportions of various metal components, except for the aluminum profiles commonly used in doors and windows. For example, except for architectural aluminum profiles such as 60 series, 70 series, 80 series, 90 series, and curtain wall series, there is no clear model distinction for industrial aluminum profiles&#;most manufacturers process according to the actual drawings of customers.

1. Anodized aluminum
2. Electrophoresis coated aluminum
3. Powder sprayed aluminum
4. Wood grain transfer aluminum
5. Fluorocarbon sprayed aluminum
6. Planed aluminum (divided into mechanical planing and chemical polishing, of which chemical polishing has the highest cost and the most expensive).
The oxide film is thin. National standards stipulate that the oxide film thickness of architectural aluminum profiles should not be less than 10um (micrometers). If the thickness is not enough, the surface of the aluminum profile will easily rust and corrode. In the spot check, some aluminum profiles without production name, factory address, production license and qualification certificate have an oxide film thickness of only 2-4um. Some don&#;t even have an oxide film. According to experts&#; calculations, the power consumption cost per ton of profiles can be reduced by more than 150 yuan for every 1um reduction in the thickness of the oxide film.
Chemical composition is unqualified. Mixing a large amount of miscellaneous aluminum and waste aluminum into aluminum profiles can greatly reduce the cost, but it will cause the chemical composition of the building aluminum profiles to be unqualified, which will seriously endanger the safety of construction projects.
Reduce the wall thickness of the profile. For the 90 series sliding window type, according to the national standard, the minimum wall thickness of the aluminum profile is not less than 1.4mm, and some Guangdong products are only 0.6 to 0.7mm. For the 46 series of floor bullet doors, the minimum wall thickness of the aluminum profile used in the national standard is not less than 1.62mm. During the random inspection, some products in Guangdong are only 0.97 to 1.18mm.
Inferior aluminum profiles greatly reduce the sealing time, reduce the loss of chemical reagents, and reduce costs, but the corrosion resistance of the profiles is also greatly reduced.
