What is a Mirror Aluminum Sheet?
Mirror aluminum sheet coil is an aluminum product processed through rolling, polishing, and other techniques to achieve a mirror-like surface effect. Its surface is specially treated to provide extremely high light reflectivity and smoothness, and it is usually delivered in sheet form (mirror aluminum sheet) or coil form (mirror aluminum coil).
The reflectivity of mirror aluminum sheet is 86%-95%. Compared with anodized mirror aluminum sheet, its surface is brighter and more attractive, but also more prone to scratches.
Mirror aluminum sheets/coils are high-reflectivity materials that can be manufactured through rolling, polishing, anodizing, or coating processes. They combine durability and aesthetics, making them suitable for a wide range of applications from building facades to solar energy systems. The main alloys include the 1000, 3000, and 5000 series, with thicknesses as low as 0.08 mm, suitable for ultra-thin designs.
Mirror Aluminum Sheet Coil Reflectivity
The most remarkable feature of mirror aluminum sheet coils is their high reflectivity, which is also the main criterion for distinguishing different grades of mirror aluminum.
The most remarkable feature of mirror aluminum sheet coils is their high reflectivity, which is also the main criterion for distinguishing different grades of mirror aluminum. Depending on the product quality and processing, the reflectivity of mirror aluminum sheets can be classified into the following levels:
- Ordinary Mirror: Reflectivity about 80%-86%.
- Standard Mirror: Reflectivity about 86%-90%.
- High Mirror: Reflectivity about 90%-93%.
- Super Mirror: Reflectivity above 95%.
It is worth noting that reflectivity is usually divided into three indicators: total reflectance, diffuse reflectance, and specular reflectance. High-quality mirror aluminum sheets have high total reflectance and low diffuse reflectance.

Mirror Aluminum Sheet Coil Production
In the production process of mirror aluminum sheet coil, the aluminum coil surface undergoes fine polishing and treatment to ensure its reflective effect and smoothness. A protective film is usually applied to prevent surface damage during transportation and handling.
Aluminum Coil Preparation
- Aluminum alloy selection: First, choose aluminum alloy raw materials suitable for mirror processing, commonly used are series 1050, 1060, and 1100. The selection of aluminum alloy directly affects the final product's quality and performance.
- Aluminum coil rolling: The aluminum alloy raw material undergoes preliminary hot rolling and cold rolling to form the basic shape of the aluminum coil. The rolling at this stage determines the thickness and basic surface quality of the aluminum coil.
Fine Polishing Process
- Surface grinding: The aluminum coil surface is subjected to multi-stage grinding to remove rough textures and surface defects generated during preliminary rolling. High-precision sandpaper or grinding machines are typically used for grinding to ensure a smooth surface.
- Polishing: The ground aluminum coil surface is finely polished. The polishing process includes using abrasive paste and polishing machines to achieve a high-gloss finish, creating a mirror effect. This process requires precise control to ensure uniform and smooth reflective effects.
Surface Treatment
- Cleaning: The polished aluminum coil undergoes thorough cleaning to remove residual abrasives and contaminants, ensuring a flawless surface.
- Protective film application: To prevent surface damage during transportation and handling, a protective film is usually applied to the aluminum coil surface. This protective film effectively prevents scratches, dirt, and other external impacts while maintaining the mirror-like gloss of the aluminum coil.
Inspection and Packaging
- Quality inspection: After production, each roll of mirror aluminum coil undergoes strict quality inspection. The inspection includes surface smoothness, reflective effect, thickness uniformity, and other factors to ensure that the product meets the specifications.
- Packaging: The inspected aluminum coil is carefully packaged. Packaging materials usually include protective paper, plastic film, and wooden pallets to ensure safe transportation. Product information and precautions are also marked on the packaging to ensure correct handling and use.
Transportation and Delivery
- Transportation: During transportation, mirror aluminum coils need to avoid severe vibration and impact to prevent damage to the protective film or scratches on the aluminum coil surface. Transport vehicles are typically equipped with appropriate protective measures to ensure the safe arrival of the aluminum coil at its destination.
- Delivery: Upon arrival at the customer's location, the aluminum coil undergoes a final inspection to ensure no issues occurred during transportation. Qualified products are delivered according to the customer's requirements, ready for use.
Mirror aluminum sheet coil, with its excellent reflective properties, superior surface treatment, and wide range of applications, is an important choice for modern decorative and functional materials.
