Aluminum Plate
Product Overview
Aluminum plates are high-performance metal sheets made of pure aluminum or aluminum alloys, featuring excellent comprehensive properties that meet the diverse needs of global buyers. They are lightweight (density only 2.7g/cm³, about 1/3 of steel), corrosion-resistant (natural oxide film on the surface, adaptable to most harsh environments), excellent in thermal conductivity and electrical conductivity, easy to process (cutting, bending, welding, and stamping), and environmentally friendly (100% recyclable without reducing performance).
Derived from its unique physical and chemical properties, it excels at balancing performance and cost, which are the key advantages you need to optimize product quality and reduce production costs. Primarily made of pure aluminum (1000 series) or aluminum alloys (3000 series, 5000 series, 6000 series), it can be customized with different temper states to meet specific application requirements. Common grades available for your selection include ASTM 1100/3003/5052/6061, GB 1060/3003/5052/6061, EN 1050A/3003/5052/6061, and JIS A1050/A3003/A5052/A6061—all of which comply with international standards and are widely recognized in global trade.
The addition of alloying elements (such as manganese, magnesium, silicon) enhances its strength, hardness, and corrosion resistance, while heat treatments like annealing (O temper) and solution treatment (T6 temper) further improve its mechanical properties, ensuring it meets the strict requirements of your different application scenarios. Its versatility extends beyond traditional industries, covering new energy, medical equipment, and precision manufacturing, making it a cost-effective and eco-friendly material. Ultimately, its exceptional performance, standardized grades, and strong adaptability make it a preferred choice for buyers worldwide, guaranteeing the production of high-quality, energy-saving, and durable products.

Surface Finishes and Protection
The surface finish of aluminum sheet significantly impacts both aesthetics and functional performance. Below are the available options.
Surface Finish Options Table
| Finish Type | Description | Features | Typical Applications |
| Mill Finish | Natural finish after rolling, no additional processing | Non-uniform reflectivity, slightly rough surface with matte metallic sheen | Internal components, applications where appearance is secondary |
| Anodized Finish | Electrochemical process thickening natural oxide layer | Enhanced corrosion resistance, increased hardness, allows coloring, wear-resistant | Architectural facades, consumer electronics, cookware, sporting goods |
| Brushed Finish | Mechanically polished to create uniform satin texture | Linear texture, reduced reflectivity, decorative satin appearance | Interior fixtures, appliance panels, decorative trim, automotive trim |
| Mirror/Polished Finish | Highly polished to reflective, mirror-like surface | Smooth, glossy, highly reflective | Decorative panels, lighting reflectors, signage |
| Powder Coating | Electrostatic application of dry powder, cured under heat | Durable, colorful, resistant to chipping and fading, wide color range | Exterior cladding, architectural elements, consumer products |
| Embossed Finish | Rollers emboss raised pattern on surface | Adds visual appeal, increases strength and rigidity, anti-slip properties | Flooring, tread plates, decorative panels |
| Chequered/Checker Plate | Raised hatch marks on one side (typically 1.5mm height) | Excellent anti-slip properties, conceals surface damage, impact-resistant | Loading bays, ramps, walkways, vehicle flooring |
| Perforated Sheet | Regular pattern of holes punched through sheet | Aesthetic appeal, light transmission, drainage, ventilation | Architectural screens, sun shades, industrial sieves, drainage covers |
| Sandblasted Finish | Surface roughened using high-speed abrasive blasting | Uniform matte texture, excellent paint adhesion | Pre-treatment for painting, decorative applications |
FAQ (Frequently Asked Questions for Aluminum Plate Buyers)
We have sorted out the most common questions from global aluminum plate buyers, providing clear and practical answers to help you solve procurement doubts efficiently and ensure the products meet your project requirements:
Q1: What is the difference between 5052 and 6061 aluminum plates? Which one should I choose for my project?
A1: Both are mainstream aluminum alloy plates, mainly differing in composition and performance. 5052 (aluminum-magnesium alloy) has excellent corrosion resistance and ductility, suitable for marine, packaging, and decorative applications (e.g., ship parts, food packaging). 6061 (aluminum-silicon-magnesium alloy) has higher strength and good weldability, suitable for structural parts, automotive components, and engineering projects (e.g., curtain walls, car body parts). For corrosion-resistant needs, choose 5052; for high-strength structural needs, choose 6061.
Q2: Can the aluminum plates be customized according to my project’s special specifications (e.g., non-standard thickness, width, or surface treatment)?
A2: Yes. We support full customization of thickness (0.1mm-600mm), width (500mm-6000mm), length (1000mm-15000mm), temper state, and surface treatment (anodizing, powder coating, etc.) according to your project drawings or technical requirements. Our technical team will provide professional advice to ensure the customized products meet your application needs.
Q3: How to ensure the aluminum plates do not get scratched or oxidized during transportation?
A4: We adopt professional packaging: each plate is covered with a PE film to prevent scratches, and packed in wooden pallets or steel frames fixed with anti-collision buffers. For long-distance sea transportation, we add moisture-proof film and waterproof covers to avoid oxidation caused by moisture, ensuring the plates arrive in good condition.
