2024 Aluminum Square Bar

2024 aluminum square bar is a high-strength aluminum alloy widely used in aerospace, automotive, machinery, and industrial fields. Its primary feature is its excellent mechanical properties, particularly its outstanding performance under high loads and impact. Although 2024 aluminum alloy has extremely high strength, its corrosion resistance is relatively poor, so appropriate protective measures need to be considered during use.

2024 Aluminum Square Bar Material Properties

• Strength: 2024 aluminum is renowned for its high strength, making it one of the strongest materials in the aluminum alloy family, capable of withstanding significant mechanical loads.
• Heat Resistance: Excellent heat resistance allows it to maintain structural stability in medium to high-temperature environments.
• Fatigue Performance: 2024 aluminum has outstanding fatigue strength, making it ideal for applications requiring high strength and fatigue resistance.
• Corrosion Resistance: Compared to other aluminum alloys (such as 5052, 6061), 2024 aluminum has relatively poor corrosion resistance, but surface treatments (e.g., anodizing) can improve its corrosion resistance.
• Machinability: Suitable for mechanical processing, cold working, and heat treatment. It can be easily cut, extruded, and drilled.
• Weldability: Welding performance is relatively low, but special techniques can overcome this limitation.
• Surface Treatment: Compatible with various surface treatment methods, including anodizing, electroplating, and polishing.

2024 Aluminum Square Bar Processing Forms

2024 Extruded Aluminum Square Bar

Processing Method:

The 2024 aluminum alloy billet is heated to a specific temperature and extruded into square bar shapes through specific dies in an extrusion press.

During the extrusion process, precise die design ensures the cross-sectional shape and dimensional accuracy of the square bar.

Features:

• Smooth Surface: The extrusion process results in a smooth and uniform surface, suitable for applications requiring high-quality appearance.
• High Dimensional Accuracy: Due to precision dies, the cross-sectional dimensional error of extruded square bars is minimal, making them suitable for parts with strict dimensional requirements.
• Large Size Production: The extrusion process is ideal for producing large-size and long rectangular bar materials.
• Versatility: After extrusion, it can be further processed, such as cutting, drilling, and surface treatment.

Cold-Processed 2024 Aluminum Square Bar

Cold-Processed Square Bar: Produced through cold processing methods, offering higher hardness and more precise dimensions.

Processing Method:

Cold processing (such as cold drawing, cold rolling, or cold forging) is applied to extruded square bars to further enhance material hardness and dimensional accuracy.

During the cold processing, no heating is required, and mechanical force is used to alter the shape and dimensions of the material.

Features:

• Higher Hardness: Cold processing increases the work hardening of the material, resulting in higher strength and wear resistance during use.
• More Precise Dimensions: Cold-processed square bars feature tighter dimensional tolerances, suitable for high-precision applications.
• Superior Surface Quality: Cold processing results in a smoother surface, reducing the complexity of subsequent processing.
• Excellent Machinability: Cold-processed 2024 aluminum square bars perform exceptionally well in precision machining, such as cutting, drilling, and milling.
