  • What are the advantages of aluminum sheet as fan blades?

    Aluminum Sheet is a flat material made of aluminum alloy, which has the characteristics of light weight, good thermal conductivity, corrosion resistance and plasticity. In daily life, we can also see aluminum sheet. The fans we often use in summer are made of aluminum sheet. The reason why aluminum sheet are used as raw materials is because of some material advantages of aluminum sheet themselves. First of all The density of the aluminum sheet is lower, which results in the fan blades made of it being lighter in weight, which greatly reduces the burden on the support structure of the fan itself and improves the portability and mobility of the fan. More importantly, the aluminum sheet itself has excellent thermal conductivity, which is a particularly important feature in fan blades. The working principle of a fan is to generate air flow through the fan blades to remove heat from the surrounding environment. Because aluminum has good thermal conductivity, it can conduct heat more effectively, allowing the fan blades to participate in the heat dissipation process more efficiently. This helps reduce the fan operating temperature and improves its heat dissipation effect, thus increasing the stability of the entire system. In addition, aluminum sheet also have excellent plasticity and processability during the manufacturing process, which shows that aluminum sheet can be more easily designed into various shapes to meet the needs of different fan blades.

  • Heat treatment steps for aluminum coils

    The heat treatment of aluminum coils refers to the planned thermal processing of aluminum coils through a series of temperature and time controlled process steps such as heating, insulation and cooling. The heat treatment process of aluminum coils is roughly divided into three parts: annealing, solution treatment and aging treatment. These heat treatment steps will have an impact on the crystal structure, hardness, strength, conductivity and corrosion resistance of aluminum coils. Annealing is the first step in heat treatment and is designed to eliminate stress and crystal defects that may occur during cold working of aluminum coils. After being held at high temperature for a period of time, the crystal structure of the aluminum coil will change, the grains will be redistributed, and some dislocations will be eliminated. This can make the aluminum coil more uniform, the lattice structure more regular, and improve the overall conductivity and plasticity of the aluminum coil. This is followed by solid solution treatment. The purpose of this step is to dissolve the alloying elements in the aluminum matrix at high temperatures to form a uniform solution. This process helps increase the hardness and strength of the aluminum coil. In solid solution treatment, the solubility of alloying elements increases with the increase of temperature, so that the alloying elements in the solid solution reach the maximum concentration. After maintaining a certain temperature for a certain period of time, a strengthening effect is formed through rapid cooling, further improving the hardness and strength of the aluminum coil. Aging treatment refers to keeping the alloy elements in the solid solution formed for a period of time at a relatively low temperature to re-precipitate and form fine precipitates. These precipitates can effectively hinder crystal slip and improve the strength and corrosion resistance of aluminum coils.

  • How to ensure the stability of aluminum coils in high temperature environments?

    The stability of aluminum coils in high-temperature environments is ensured through a variety of processes and alloy designs. The harsh conditions faced by aluminum coils in high-temperature environments include, inter alia, material softening, oxidation, thermal expansion and interfacial reactions with different substances. First of all, appropriate alloy design is the prerequisite to ensure the high-temperature stability of aluminum coils. Generally, a certain amount of alloying elements, such as copper, magnesium, zinc, etc., are added to aluminum alloys to form strengthening sections and enhance the thermal stability of the material. Such a design can improve the hardness, tensile power and creep resistance of aluminum coils at excessive temperatures. Secondly, the heat treatment system plays a key role in improving the high-temperature stability of aluminum coils. By controlling the heating, protection and cooling strategies, the crystal structure of the aluminum coil can be adjusted, the grain distribution is optimized, and the stability of the crystal lattice and resistance to thermal expansion can be improved. Surface coating is an important means to ensure that aluminum coils resist oxidation in high temperature environments. Some packaging in high-temperature environments, such as automobile engine parts, require the surface of the aluminum coil to withstand high-temperature oxidation corrosion. By using an anti-oxidation coating, the oxidation reaction of the aluminum coil base plate can be correctly avoided and its balance in high-temperature environments can be improved.
