Large industrial fans are widely used in daily life and industrial production. Their excellent cooling and ventilation performance enables large industrial fans to fully function in the hot summer. Large industrial fans can form a full range of ground coverage and a three-dimensional circulation of air. The streamlined blades manufactured by aerodynamic principles can better drive the air. In addition to the shape of the blades, the material of the blades is also a very important part. . Magnesium aluminum alloy is usually used as the raw material for manufacturing large industrial fan blades, which can better ensure the performance of the fan blades. Then, why can magnesium aluminum alloy be used to make the blades of industrial large fans? Today, let’s analyze the advantages of making industrial fan blades made of magnesium aluminum alloy.
1. The density of magnesium aluminum alloy is small
Magnesium metal is a kind of very low density among all structural metals in the world, so its mass is also very light. Its density is about 1.8g/cm3, which is equivalent to 2/3 of aluminum alloy, 1/4 of steel, and 1 of zinc. /4 or so. Even plastics are not as light as magnesium-aluminum alloys. Under the same strength requirements, magnesium-aluminum alloy parts can be made lighter and thinner than plastic.
The components of magnesium-aluminum alloy are metallic magnesium and metallic aluminum, of which metallic magnesium accounts for about 90% of the weight. Therefore, magnesium-aluminum alloy inherits the light weight characteristics of metallic magnesium, and its weight is very light, suitable for making large industrial fans The blades are not only convenient for processing, and this lightweight property can increase the speed of the fan blades, and the safety is also better.
2. Magnesium aluminum alloy has high specific strength
"The ratio of the tensile strength of a material to the apparent density of the material is called the specific strength, which is the strength of the material (the force per unit area when it is broken) divided by its apparent density. The higher the specific strength, the lighter the material used to achieve the corresponding strength. High-quality structural materials should have high specific strength to meet the strength requirements with a smaller cross-section as much as possible, and at the same time, the self-weight of the structure can be greatly reduced.
The specific strength of magnesium-aluminum alloy is very high, which proves that it is light in weight and has good load-bearing capacity, which is suitable for making large industrial fan blades.
