What is an Aluminum Plate and What Is Its Thickness Range?
An aluminum plate is a flat, rectangular sheet made from aluminum ingots through rolling and processing. It typically has a thickness greater than 0.2mm and less than 500mm, with a width over 200mm and a length under 16 meters. With the development of large-scale equipment, some aluminum plates can now reach a maximum width of up to 600mm. Aluminum plates are categorized into several types, including pure aluminum plates, alloy aluminum plates, thin plates, medium and thick plates, and patterned aluminum plates. They are widely used in various industries due to their lightweight, durability, and corrosion resistance.Common Classification of Aluminum Sheets
Aluminum sheets are generally divided into two main categories: by alloy composition and by thickness. 1. **By Alloy Composition**: - High-purity aluminum plate (made from aluminum with more than 99.9% purity) - Pure aluminum plate (mainly composed of pure aluminum) - Alloy aluminum plate (a combination of aluminum and other alloys such as copper, manganese, silicon, magnesium, etc.) - Clad or welded aluminum plate (special materials created by combining different layers) - Aluminum-clad aluminum sheet (an aluminum sheet with a thin layer of aluminum on its surface for special applications) 2. **By Thickness (in mm)**: - Sheet (aluminum sheet): 0.15–2.0 - Standard sheet (aluminum sheet): 2.0–6.0 - Aluminum plate: 6.0–25.0 - Thick plate (aluminum plate): 25–200Applications of Aluminum Plates
Aluminum plates have a wide range of uses, including: 1. Lighting systems 2. Solar reflectors 3. Building exteriors 4. Interior design (ceilings, walls, etc.) 5. Furniture and cabinets 6. Elevators 7. Signage and nameplates 8. Photo frames 9. Household appliances (refrigerators, microwave ovens, audio devices) 10. Aerospace and defense (such as China's large aircraft and space programs) 11. Mechanical parts manufacturing 12. Mold production 13. Chemical and insulation pipeline coatings 14. High-quality shipbuildingClassification of Aluminum Alloys
Aluminum alloys are classified into nine series, each with unique properties and applications. The most commonly used include: - **1 Series**: Industrial pure aluminum - **2 Series**: Aluminum-copper alloys - **3 Series**: Aluminum-manganese alloys - **4 Series**: Aluminum-silicon alloys - **5 Series**: Aluminum-magnesium alloys - **6 Series**: Aluminum-magnesium-silicon alloys - **7 Series**: Aluminum-zinc-magnesium-copper alloys - **8 Series**: Other alloys - **9 Series**: Spare alloys For example, the 7075-T651 aluminum plate belongs to the 7 series and is known for its high strength and good mechanical properties, making it ideal for aerospace and structural applications.Chemical Composition and Properties
The chemical composition of 7075-T651 aluminum plate includes: - Aluminum (Al): Balance - Silicon (Si): 0.25% - Copper (Cu): 0.10% - Magnesium (Mg): 2.2–2.8% - Zinc (Zn): 0.10% - Manganese (Mn): 0.10% - Chromium (Cr): 0.15–0.35% - Iron (Fe): 0.4% It also exhibits excellent mechanical properties: - Tensile strength (σb): 170–305 MPa - Yield strength (σ0.2): ≥65 MPa - Elastic modulus (E): 69.3–70.7 GPa - Annealing temperature: 345°C These characteristics make it suitable for high-performance applications where strength and reliability are essential.Galvanized Nut Bolt,Hot Dip Galvanized Nut,Hdg Hex Nuts,Galvanized Hex Nut Fastener
