Three aluminum alloys, 1xxx series, 3xxx series and 5xxx series, are widely used in aluminum composite panels for building decoration.
Mn is the main alloy element of this alloy in the 3xxx series. Its strength is more than 20% higher than that of the 1xxx series alloy. It is widely used in roofs, curtain walls, awnings, and highway signs. Commonly used alloys include 3003, 3015, and other states.
The main alloy of the 5xxx series is Mg. When magnesium is used as the main alloying element or used together with manganese, it can form a work-hardenable alloy with medium or high strength.
As a hardener, magnesium is largely more effective than manganese. Approximately 0.8% magnesium is as effective as 1.25% manganese, and can be added to aluminum in much higher quantities, giving this family of alloys good properties. It has good welding performance and good corrosion resistance in marine air. It is widely used in construction and complex-shaped special-shaped parts, signs, and image products. Commonly used alloys include 5005, 5754 and other states.
The aluminum alloy plates used in building decoration are mainly 3xxx series aluminum-manganese alloys. In practical applications, 5xxx series aluminum-magnesium alloys are relatively hard. When special-shaped parts need to be deformed and processed multiple times, 3xxx series alloys with better processing performance are still the main ones.

Characteristics of architectural decorative aluminum panels
Aluminum alloy decorative panels have the advantages of light weight, non-combustibility, good durability, convenient construction, and good decorative effect. They are suitable for decoration of indoor and outdoor walls and columns of public buildings. Colors include natural color, golden yellow, bronze, brown, etc.
Aluminum alloy decorative panels are decorative decorative panels produced from aluminum and aluminum alloys through processes such as casting, hot rolling, cold rolling, and subsequent processing.
Aluminum composite panel refers to a panel made of aluminum and plastic. Specifically, it is a plate made of aluminum plate and plastic core material bonded and compounded by a special adhesive under certain process conditions. In practice, the aluminum plates used as the front and back are usually painted first, and then compounded with the plastic core material. The front panel is generally coated with a decorative coating, and the back panel is coated with a protective coating. Regarding the structure of aluminum composite panels, it is generally a sandwich structure, which is a more vivid metaphor - two layers of aluminum panels with a layer of plastic core material sandwiched between them. In fact, the structure of aluminum composite panels is much more complex.
There are many varieties of aluminum composite panels, which are usually classified according to use, product function and surface decoration effect.
(1) Classification by product function
1) Fire-proof board: Use flame-retardant core material, and the product's combustion performance reaches flame-retardant grade (B1 level) or non-flammable grade (A level); at the same time, other performance indicators must also meet the technical specifications of aluminum composite panels.
2) Antibacterial and mildew-proof aluminum composite panels: Coatings with antibacterial and bactericidal effects are applied to aluminum composite panels to control microbial activity and reproduction and ultimately kill bacteria.
3) Antistatic aluminum composite panel: The antistatic aluminum composite panel is coated with antistatic paint. The surface resistivity is below 109Ω, which is smaller than the surface resistivity of ordinary aluminum composite panels. Therefore, it is not easy to generate static electricity, and the dust in the air is also Not easy to adhere to its surface.
(2) Classification according to surface decoration effect
1) Coated decorative aluminum composite panel: Various decorative coatings are coated on the surface of the aluminum panel. Commonly used coatings include fluorocarbon, polyester, and acrylic coatings, which mainly include metallic, plain, pearlescent, fluorescent and other colors. They have a decorative effect and are the most common ones on the market.
variety.
2) Oxidation and coloring aluminum composite panels: The aluminum alloy panels are timely treated by anodizing and have unique colors such as rose red and bronze, which have a special decorative effect.
3) Film decorative composite panel: The color pattern film is applied according to the set process conditions and relies on the action of the adhesive to make the color pattern film adhesive stick on the aluminum plate coated with primer or directly on the degreased aluminum plate. The main varieties include Gang pattern, wood grain boards, etc.
4) Color printed aluminum composite panels: Use advanced computer phototypesetting and printing technology to print different patterns with color ink on transfer paper to produce various imitation natural patterns, and then indirectly copy them on the aluminum composite panels through thermal transfer technology. Various imitation natural patterns. It can meet the creativity of designers and the personalized choices of owners.
5) Brushed aluminum composite panel: An aluminum alloy panel with a brushed surface is used. Commonly used are gold brushed and silver brushed products, which bring different visual experiences to people.
