What is an Aluminum Plate and Its Thickness Range
An aluminum plate is a flat material made from aluminum ingots through rolling and processing. It typically has a thickness greater than 0.2mm and less than 500mm, with a width exceeding 200mm and a length under 16 meters. In recent years, with the development of large-scale equipment, aluminum plates with widths up to 600mm have become more common. Aluminum plates are categorized into several types, including pure aluminum plates, alloy aluminum plates, thin plates, medium and thick plates, and patterned plates. These variations depend on the composition and intended use.Common Classification of Aluminum Sheets
There are two main ways to classify aluminum sheets: 1. **By Alloy Composition**: - High-purity aluminum plate: Made from aluminum with over 99.9% purity. - Pure aluminum plate: Composed mainly of aluminum. - Alloy aluminum plate: Made from aluminum mixed with other elements, such as copper, manganese, silicon, magnesium, etc. - Clad or welded aluminum plate: Special-purpose materials created by combining different materials. - Aluminum-clad sheet: An aluminum sheet with a thin layer of aluminum on its surface for specific purposes. 2. **By Thickness (in mm)**: - Sheet: 0.15–2.0 mm - Regular sheet: 2.0–6.0 mm - Aluminum plate: 6.0–25.0 mm - Thick plate: 25–200 mmApplications of Aluminum Plates
Aluminum plates are widely used in various fields, such as lighting, solar reflectors, building exteriors and interiors (ceilings, walls), furniture, elevators, signs, nameplates, photo frames, household appliances (refrigerators, microwave ovens, audio systems), aerospace and military industries (like China’s large aircraft and space programs), mechanical parts, mold manufacturing, chemical and insulation pipeline coatings, and high-quality shipbuilding.Classification of Aluminum Sheets by Grade
Aluminum alloys are classified into different series, each with unique properties. For example, 7075-T651 is a type of aluminum plate known for its high strength. The first digit indicates the primary alloying element: - 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: Miscellaneous alloysChemical Composition and Properties
The typical chemical composition of an 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% Its mechanical properties include: - 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 aluminum plates versatile and suitable for a wide range of industrial and commercial applications.ZHENAN NEW METAL CO .,LTD , https://www.zanewmaterial.com
