How Much Do You Know About Aluminum Clad Steel Sheet
With the continuous development of materials science, various new composite materials emerge in an endless stream, and the aluminum clad steel sheet is one of the most popular ones. It cleverly combines the advantages of aluminum and steel, and shows unique application value in many fields.
1. Structure of aluminum-steel composite panels
Aluminum-steel composite panels are generally composed of aluminum layers and steel layers. Common structural forms include symmetrical structures and asymmetrical structures.
Symmetrical structure means that the aluminum layer is on both sides and the steel layer is in the middle. This structure makes the performance of the composite plate more balanced in all directions; the asymmetric structure sets the aluminum layer and the steel layer in different positions according to the actual use requirements.
In order to better combine the aluminum layer and the steel layer, a transition layer may be added in the middle. The material of the transition layer is usually a metal that can be well combined with aluminum and steel, such as pure aluminum, pure titanium or some specific alloy materials.
Through special process treatment, such as explosive compounding, rolling compounding, etc., a strong metallurgical bond is formed between the layers, thereby ensuring the stability of the overall performance of the composite plate.
2. Selected materials
The aluminum layer is mostly made of aluminum alloys with good corrosion resistance, thermal conductivity and processing performance. Common ones include 1000 series pure aluminum, such as 1050, 1060, etc. They have high purity, excellent corrosion resistance and conductivity, and are widely used in occasions where strength requirements are not high.
There are also 3000 series aluminum-manganese alloys, such as 3003, which have good processing performance and moderate strength; 5000 series aluminum-magnesium alloys, such as 5052, have high strength and excellent corrosion resistance, and are more common in some applications that have certain requirements for strength and corrosion resistance.
The steel layer usually uses low-carbon steel, such as Q235. Low-carbon steel has the advantages of good comprehensive performance, low cost and wide application range. Its high strength and good plasticity can provide solid support for the composite board and meet the requirements of strength and bearing capacity under different working conditions. At the same time, low-carbon steel and aluminum alloy can be well combined in the composite process to form a stable and reliable composite structure.
3. Application fields
Construction field
Aluminum-steel composite panels can be used for the facade decoration of high-end office buildings, large shopping malls, airport terminals, high-speed rail stations and other buildings. Aluminum-steel composite panels can also be used as roofing materials. In addition, aluminum-steel composite panels are also used in partition walls, ceilings and other parts inside buildings, which can meet the functional requirements of fire prevention and sound insulation.
Transportation field
In automobile manufacturing, aluminum-steel composite plates can be used for automobile body structural parts, doors, engine hoods and other parts. In shipbuilding, aluminum-steel composite plates can be used for ship superstructures, decks and other parts. At the same time, for some special-purpose ships, such as ships operating in marine environments, the seawater corrosion resistance of aluminum-steel composite plate with marine grade aluminum sheet layer is of great significance.
Electronic and electrical field
The good electrical conductivity and electromagnetic shielding performance of aluminum-steel composite plates make them used in the field of electronic and electrical appliances. In the internal structural parts of some electrical products, aluminum-steel composite plates can also play the advantages of their strength and processing performance to meet the design and manufacturing requirements of the products.
