The main role of fans is ventilation, dust extraction and cooling, and is currently widely used in factories, mines, tunnels, cooling towers, vehicles, ships and buildings. Fan blade is the basic and key component in the fan, the selection of blade material plays an important role in the stable operation of the fan, its good design, stable quality and superior performance are important factors to ensure the normal operation of the fan.
5052 aluminum plate is an aluminum-magnesium alloy, the main alloying element is magnesium, the material has a certain strength, high plasticity, good corrosion resistance, good weldability. The fan blade adopts 5052 aluminum alloy with high strength, good heat dissipation, good shock absorption, large capacity to withstand impact load, good corrosion resistance to organic matter and alkali, and is favored by the market.
Mechanical properties of 5052 aluminum plate for fan blades:
Conditional yield strength σ0.2 (MPa)≥90
tensile strength(σb ) ：170～305Mpa
Elastic modulus(E)： 69.3～70.7Gpa
The selection of blade material is the key to blade design, and excellent material is an important guarantee for the fan to have excellent characteristics. It is mainly considered from the following aspects
1.Appearance quality. The surface of the aluminum plate is flat, the material is uniform, there is no peeling, bubbles, rough surface and local mechanical damage, and there are no cracks, corrosion spots and traces of nitrate salt on the surface of the aluminum plate.
2.Mechanical properties. The performance is stable and reliable, and the post-processing quality is excellent.
