What is an aluminum profile?
Aluminum extrusion is a material with a specific cross-sectional shape produced from aluminum and aluminum alloys through an extrusion process. Its production process includes melting, casting, extrusion molding, heat treatment and surface treatment. Aluminum profiles are widely used in many fields such as construction, industry, transportation, electronics, and aerospace due to their unique properties. Let's firts briefly review the production process of aluminum profile and its properties.
The production process of aluminum profiles:
- Melting and casting: First, aluminum ingots are mixed with other alloying elements in proportion and heated and melted to form aluminum alloy melt. After refining and degassing, the melt is cast into aluminum bars or ingots.
- Extrusion: The cast aluminum bar is heated to an appropriate temperature, put into an extruder, and extruded through a die into an aluminum profile of the desired cross-section shape. This step determines the basic shape and size of the aluminum profile.
- Heat treatment: After extrusion, aluminum profiles need to undergo heat treatment, such as quenching and aging, to enhance their mechanical properties and hardness.
- Surface treatment: In order to enhance the corrosion resistance and aesthetics of aluminum profiles, surface treatments such as anodic oxidation, electrophoretic coating, powder coating, etc. are often carried out.
Properties of aluminum profiles:
- Light weight: Aluminum has a density of approximately 2.7g/cm³, about one-third that of steel, giving aluminum extrusions an advantage in applications where weight reduction is required.
- High strength: Through alloying and heat treatment processes, aluminum profiles can acheive high strength to meet the needs of various applications.
- Corrosion resistance: Aluminum tends to form a natural oxide film in the air, which gives aluminum profiles good corrosion resistance. Further surface treatment can greatly enhance its durability.
- Good electrial and thermal conductivity: Aluminum conducts electricity and heat well, making it excellent for electrical and heat transfer applications.
- Good processing performance: Aluminum profiles are easy to cut, stamping, bending, welding and other mechanical processing, excellent formability, can adapt to the design of complex structures.
