In the realm of aluminum alloys, 3004 aluminum alloy stands out as a versatile material widely used in various industries. This article will provide you with a comprehensive understanding of 3004 aluminum alloy, including its composition, characteristics, processing techniques, alloy states, and applications.
3004 alloy mainly contains magnesium and manganese as its primary alloying elements. It is the go - to material for what is commonly referred to as aluminum - magnesium - manganese plates in architectural decoration and roofing applications.
| Feature | Description |
| Strength | Has higher strength compared to 3003 alloy. |
| Workability | Exhibits excellent workability in the annealed state. |
| Heat Treatment | Cannot be strengthened through heat treatment. |
| Anodizing | Suffers from severe anodizing color differences, thus is generally not suitable for anodizing processing. |
Due to the presence of magnesium in 3004 alloy, the main processing method is hot - rolling. This technique helps in achieving the desired properties and form of the alloy for different applications.
Element | Composition Range (%) |
Aluminum (Al) | Balance (≈97.5–98.5%) |
Manganese (Mn) | 1.0–1.5% |
Silicon (Si) | ≤0.35% |
Iron (Fe) | ≤0.7% |
Magnesium (Mg) | ≤0.25% |
Copper (Cu) | ≤0.20% |
Zinc (Zn) | ≤0.25% |
Other Elements | ≤0.15% (each ≤0.05%) |
| Alloy | Explanation |
| O | Annealed to the softest state. |
| H18 | Grain - hardened to a fully hard state. |
| H24 | Grain - hardened and then annealed to a semi - hard state. |
Thermal insulation coils: Provide effective thermal insulation in various construction and industrial settings.
Colored aluminum coils: Used in applications where aesthetic appeal along with the properties of aluminum is required.
Chassis and cabinets: Offer strength and durability for protecting internal components in electronic and mechanical equipment.
Honeycomb panels: Provide lightweight yet strong structural elements in aerospace, automotive, and construction industries.
Curtain wall aluminum plates: Enhance the appearance and weather resistance of building facades.
Patterned plates and orange - peel patterns: Used for decorative purposes or in applications where anti - slip or aesthetic textured surfaces are needed.
Aluminum foil meal boxes: Ideal for food packaging due to its barrier properties against oxygen, moisture, and light.
Honeycomb cores: Contribute to the lightweight and high - strength characteristics of composite structures.
Ventilation ducts: Provide corrosion resistance and durability in ventilation systems.
