The material of the fan blades directly affects the efficiency of the cooling fan. Plastic fan blades are light and low-cost, but are slightly weaker in terms of high temperature resistance and heat dissipation performance, and are suitable for general environments. Metal fan blades, such as aluminum alloy fan blades, are often used in the designs of dc centrifugal fan manufacturers. They are more stable in high temperature environments and can effectively improve the heat dissipation effect.

For devices that require high air volume, ac axial fan manufacturers usually use optimized blades to ensure stable airflow and efficient heat dissipation. In contrast, brushless dc fan suppliers often recommend the use of lighter materials to match brushless motors to improve fan efficiency and extend service life.

Choosing the appropriate material for the fan blades can effectively enhance the overall performance of the fan, ensuring the heat dissipation effect of the equipment and its long-term stable operation.
