What is mirror aluminum sheet
Mirror aluminum sheet is a kind of aluminum alloy plate with specially treated surface, which is characterized by high gloss and reflectivity, similar to the effect of a mirror.
This effect is achieved through a series of refined processing techniques, including polishing, electrolytic polishing or coating a layer of transparent coating with high reflectivity.
Mirror aluminum sheet not only has good decorative properties, but also has the characteristics of aluminum itself, such as light weight and corrosion resistance.

What are the materials used to make mirror aluminum sheets?
The materials used to make mirror aluminum sheets are mainly aluminum alloys. Specifically, they include the following common aluminum alloy grades:
1000 series pure aluminum plates: such as 1050, 1060, 1070 and 1100 aluminum sheet.
These grades of aluminum plates have high aluminum content, relatively simple production processes, and relatively economical prices.
They are the most popular choices in the market. They are characterized by good conductivity and corrosion resistance, and are suitable for basic mirror processing needs.
3000 series alloy aluminum plates: such as 3003, 3004, 3104, 3105, etc. 3000 series aluminum plates are aluminum-manganese alloys, with a hardness of about 20% higher than that of 1000 series aluminum plates.
They have a wider range of application scenarios than 1000 aluminum plates, but the price of 3000 aluminum plates is slightly higher than that of 1000 series aluminum plates.
5000 series alloy aluminum plates: The main component contains magnesium, and common grades include 5005, 5052, 5754, etc.
5000 series aluminum sheet has low density, high tensile strength and good elongation.
It is often used in aviation and conventional industries. Due to its good mechanical properties and processing properties, it is also very suitable for making mirror effects, especially in situations where higher performance requirements are required.

Aluminum plate mirror treatment process
The mirror treatment process of aluminum plate mainly includes the following steps and methods:
Rolling method:
This is a commonly used method for producing mirror aluminum sheet.
By using mirror rollers to continuously roll the alloy aluminum plate, the surface of the aluminum plate presents a mirror-like smooth effect.
During the rolling process, the accuracy of the hot-rolled strip and the extruder, especially the precision of the roller equipment, has a decisive influence on the reflectivity of the mirror aluminum sheet.
Grinding and polishing:
This is one of the key steps in mirror treatment.
Through physical grinding, grinding tools and polishing agents are used to remove minor flaws on the surface of the plate to make it extremely smooth.
This process requires delicate operation to ensure that the characteristics and strength of the material itself are not damaged.
Spraying and drying:
As the first step in surface treatment, according to the requirements of the mirror effect, select appropriate spraying materials and drying processes.
After uniform spraying and drying, the mirror performance and protective layer of the aluminum plate can be enhanced to prevent oxidation.
Anti-oxidation polishing treatment:
In order to improve the durability and cleanliness of the mirror aluminum sheet, the surface also needs to be treated with anti-oxidation.
This step can prevent the mirror performance of the plate from deteriorating during use and improve its corrosion resistance and wear resistance.
Electrolytic polishing:
This is a chemical treatment method that uses electrolysis to form a uniform and dense oxide film on the surface of aluminum products, which not only improves the surface brightness but also enhances its corrosion resistance.
This method is particularly suitable for application scenarios that require extremely high mirror effects and surface quality.
In summary, the production of mirror aluminum sheets is a complex process that combines physical and chemical treatments, aiming to achieve a high degree of smoothness and reflectivity on the surface of aluminum plates through different technical means, while ensuring its durability and aesthetics.

What are the types of mirror aluminum sheets?
Film-coated mirror aluminum sheet:
The mirror effect is achieved by attaching a layer of high-reflectivity protective film on the surface of the aluminum plate.
This method is low-cost, but the durability is relatively poor. It is suitable for short-term use or cost-sensitive products.
Polished mirror aluminum sheet:
After mechanical polishing, the surface is as smooth as a mirror, but there may be no additional protection treatment, so the mirror effect may gradually decrease over time.
The price is relatively cheap and suitable for mid- and low-end applications.
Oxidized mirror aluminum sheet:
On the basis of polishing, the surface is anodized to form a transparent and hard oxide film, which greatly improves the durability and corrosion resistance of the mirror effect.
It is a high-end product and is commonly used in decoration and industrial applications with high quality requirements.

Casting production process and its introduction
The purpose of melting and casting is to produce alloys with satisfactory composition and high purity of melt, so as to create favorable conditions for casting alloys of various shapes.
Melting and casting process steps: batching --- feeding --- melting --- stirring after melting, slag removal --- pre-analysis sampling --- adding alloy to adjust the composition, stirring --- refining --- static Setting——Guide furnace casting.
Hot rolling production process and its introduction
- 1. Hot rolling generally refers to rolling above the metal recrystallization temperature;
- 2. During the hot rolling process, the metal has both hardening and softening processes. Due to the influence of deformation speed, as long as the recovery and recrystallization process is too late, there will be a certain work hardening;
- 3. The recrystallization of the metal after hot rolling is incomplete, that is, the coexistence of recrystallized structure and deformed structure;
- 4. Hot rolling can improve the processing performance of metals and alloys, reduce or eliminate casting defects.
- 1. The casting and rolling temperature is generally between 680°C and 700°C. The lower the better, the stable casting and rolling line usually stops once a month or more to re-stand. During the production process, it is necessary to strictly control the liquid level of the front tank to prevent low liquid level;
- 2. Lubrication uses C powder with incomplete combustion of gas for lubrication, which is also one of the reasons for the dirty surface of casting and rolling materials;
- 3. The production speed is generally between 1.5m/min-2.5m/min;
- 4. The surface quality of products produced by casting and rolling is generally relatively low, and generally cannot meet products with special physical and chemical performance requirements.
- 1. Cold rolling refers to the rolling production method below the recrystallization temperature;
- 2. There will be no dynamic recrystallization during the rolling process, and the temperature will rise to the recovery temperature at most, and the cold rolling will appear in a work hardening state, and the work hardening rate will be large;
- 3. The cold-rolled sheet and strip have high dimensional accuracy, good surface quality, uniform structure and performance, and products in various states can be obtained with heat treatment;
- 4. Cold rolling can roll out thin strips, but at the same time, it has the disadvantages of high energy consumption for deformation and many processing passes.
- 1. Finishing is a processing method to make the cold-rolled sheet meet the customer's requirements, or to facilitate the subsequent processing of the product;
- 2. The finishing equipment can correct the defects produced in the hot rolling and cold rolling production process, such as cracked edge, oily, poor plate shape, residual stress, etc. It needs to ensure that no other defects are brought into the production process;
- 3. There are various finishing equipments, mainly including cross-cutting, slitting, stretching and straightening, annealing furnace, slitter, etc.
