The material of the fan casing usually depends on the specific application and requirements. Common fan casing materials include but are not limited to the following:
Cast iron: Cast iron is a common material for fan casing, with good strength and wear resistance, suitable for some larger industrial fans.
Steel: Stainless steel, carbon steel and other steel materials are commonly used for fan casings, which have good corrosion resistance and strength, and are suitable for environments with high material requirements.
Aluminum alloy: Aluminum alloy has a relatively light weight and good thermal conductivity, making it suitable for some occasions that require lightweight and good heat dissipation performance.
Plastic: Some small fans or fan casings with special requirements may use plastic materials such as polypropylene, polyvinyl chloride, etc.
Composite materials: Some high-performance fans may use composite materials such as fiberglass reinforced plastic (FRP), which have good strength and corrosion resistance.
When choosing the material for the fan casing, multiple factors such as working environment, usage requirements, and cost need to be considered to ensure the performance and reliability of the fan.
