Everything about Aluminum Profile

Aluminum profiles make full use of the excellent ductility of aluminum. Aluminum products with specific shapes and sizes are formed through extrusion, stretching, die-casting and other processing processes. They have the advantages of light weight, high strength, corrosion resistance and other advantages.

Standard hollow aluminum profile

Usually, hollow standard aluminum alloy profiles are in tubular shape. These aluminum tube products can have different cross-sectional shapes, such as square tubes, round tubes, rectangular tubes, etc. These profiles typically adhere to international or national standards like ASTM, EN, etc., ensuring their quality and dimensional consistency.

Hollow profiles are generally lighter because they are hollow inside, making them more suitable where structural loads need to be reduced or where a lightweight design is required. In addition, the space inside the hollow profile can also be used to hide wires, pipes and other facilities, improving the overall aesthetics.Quick Quote

Standard solid aluminum profile

Solid aluminum alloy profiles are profiles made of aluminum alloy and there is no hollow structure inside the cross-section, typically in the form of solid aluminum bar rods. Common shapes of solid aluminum alloy profiles include square profiles, round profiles, angle profiles, etc. Their size and shape can be customized according to specific engineering requirements.

This type of profile usually has higher strength and stiffness and is suitable for applications that need to withstand greater pressure or require greater stability, such as structural support that needs to withstand greater pressure or for high loads.Quick Quote

Key quality indicators of aluminum profiles

1. Appearance quality requirements: there are no defects such as electric burns or oxide film peeling on the surface of anodized materials; the paint film is uniform, clean and smooth, without wrinkles, cracks, bubbles, flowing, inclusions and peeling marks; aluminum alloy building profile coating treatment, Avoid scratches, collisions and corrosion.

2. Wall thickness: the wall thickness of the profile is one of the main factors affecting the strength of the workpiece. The main section is the stressed part of the project. For example, the minimum nominal wall thickness of the main profile of an exterior window should not be less than 1.4mm.

3. Film thickness requirements: the surface of extruded aluminum alloy profiles is not very corrosion-resistant and needs to be treated to increase corrosion resistance, wear resistance and aesthetics. The thickness of the anodized aluminum film is divided into AA10, AA15, AA20 and AA25; the thickness of the electrophoretic coating aluminum film is divided into ABS, the minimum local thickness of powder spraying is more than 40um, and fluorocarbon spraying has different requirements for layer thickness.

4. Chemical composition and mechanical properties: the chemical composition and mechanical properties of aluminum alloy profiles vary, and customers should check them one by one according to the standards (contract terms).

5. Color difference: there are differences in color brands and supply status. It is recommended that the impact of color difference on the building structure should be considered when selecting the alloy plate number and supply status.

6. Resistance to salt spray corrosion, wear, waiting and mortar, etc.: this is an important technical parameter of aluminum alloy profiles. It reflects the performance of aluminum alloy profiles and affects its use.

Aluminum profile production and processing

The aluminum extrusion process starts with a cylindrical aluminum billet, which is heated to temperatures between 400 and 500 degrees Celsius. The blank is then pressed through a mold with carefully designed contours. The mold shapes the aluminum into the desired cross-sectional shape, which can be as simple as a rectangle or as complex as a hollow tube with multiple interior chambers.

The extruded aluminum is then cooled by spraying water, which improves its mechanical properties and makes it easier to handle. During the cooling process, aluminum may undergo quenching to increase its strength and hardness.

Aluminum profile CNC machining

Aluminum extrusion CNC machining is the process of using computer-controlled machines to shape aluminum extrusion parts to a specific design. The process of CNC machining of aluminum extrusion consists of three main steps: design, programming and machining.

First, the design is created using computer-aided design (CAD) software, which can create precise dimensions and specifications. Next, the design is programmed into a CNC machine, which uses a series of tools to cut, shape and form the aluminum extrusion into the desired shape. Finally, the machined parts are usually finished by grinding, polishing or anodizing.

One of the main advantages of CNC machining of aluminum extrusion is the creation of complex shapes and models with high precision and consistency, suitable for parts that are difficult to manufacture using traditional methods. This process is highly automated, improves production efficiency and reduces labor costs. Another benefit is the versatility to produce parts in a variety of sizes and shapes to meet the needs of different industries.
