5005 aluminum sheet
1.Application Scenarios
Building Decoration: Curtain wall panels, indoor and outdoor ceilings, wall decorative panels, stair railings, suitable for various architectural styles with excellent decorative texture
Signage Production: Road signs, commercial billboards, scenic area guide signs, with clear handwriting and sun-resistant non-fading after anodizing
Transportation Facilities: Bus stop canopies, subway station decorative parts, highway guardrail accessories, weather resistance suitable for complex outdoor environments
Home Appliances & Furniture: High-end lamp housings, furniture decorative frames, kitchen equipment panels, balancing aesthetics and corrosion resistance needs
Industrial Parts: Lightweight equipment housings, pipeline shields, radiator covers, using lightweight advantages to reduce the overall weight of equipment
2.Product Advantages
Excellent Weather and Corrosion Resistance: Al-Mg alloy material, naturally forming a dense oxide film on the surface, salt spray resistant, moisture resistant, acid and alkali resistant, with outdoor service life up to 15 years or more
Good Compatibility with Anodizing: A uniform oxide film is formed on the surface after anodizing, which can be dyed in various colors, with strong adhesion and full color, dual improvement of decoration and protection
Superior Processability: Easy to bend, cut, stamp and weld, good dimensional stability after processing, no rebound or deformation, suitable for complex shape processing
Lightweight and High Strength: Density is only 2.68g/cm³, strength is better than pure aluminum and ordinary aluminum-manganese alloy, balancing convenient installation and structural bearing needs
Balanced Cost-Effectiveness: Performance is close to 5052 alloy, more advantageous in price, suitable for bulk construction engineering and industrial production procurement

4.Production process
Raw Material Proportioning and Melting: Mix aluminum, magnesium and trace alloying elements in precise proportions, put into the furnace for high-temperature melting, and remove impurities through refining agents to ensure alloy purity
Ingot Casting: Pour the refined aluminum alloy liquid into flat ingots, and perform homogenization treatment to eliminate alloy composition segregation and optimize internal structure
Hot Rolling Billet: Heat the ingot to 400-500℃ for hot rolling, initially reduce thickness, refine grains, and improve alloy mechanical properties
Cold Rolling Finishing: Perform multiple passes of cold rolling at room temperature, gradually roll to the target thickness, strictly control dimensional tolerance, and improve surface finish
Annealing and Tempering: Conduct low-temperature annealing as needed to eliminate cold rolling internal stress, temper to H24 (half-hard state) or O (soft state), and ensure stable performance
Finishing and Packaging: Trim, flatten and cut the sheet to fixed size, after surface cleaning treatment, it can be packaged and stored only after passing the inspection
5.FAQ
Q1:What surface treatments can be applied to 5005 aluminum sheet?
A1:Anodizing (dyeable) is preferred, and PVDF coating, polyester coating, film covering, wire drawing and other treatments are also available. Different treatment methods can further improve the decorative effect or weather resistance, suitable for different application scenario needs.
Q2:What should be noted when storing 5005 aluminum sheet?
A2:It should be stored in a dry and ventilated warehouse, avoiding rain, sun exposure and humid environment; the sheets should be stacked flat, with a stacking height not exceeding 2 meters to prevent deformation of the bottom sheets; sheets of different specifications and states should be stored separately to avoid mixing.
Q3:What is the difference between H24 and O tempers of 5005 aluminum sheet?
A3:H24 is half-hard state, with high strength and moderate hardness, suitable for decorative parts and accessories that require certain structural strength; O is soft state, with excellent ductility, easy for deep drawing, complex bending and other processing, suitable for products with high forming difficulty.
Q4:Does 5005 aluminum sheet meet food contact standards?
A4:Regular 5005 aluminum sheet is not recommended for direct food contact scenarios; if it needs to be used in food-related fields, custom food-grade 5005 aluminum sheet is required, the impurity content is strictly controlled during the production process, and it can be used only after passing the test and meeting food contact safety standards.
