What material is used for the fan blades

The material selection of fan blades usually depends on factors such as required mechanical strength, operating environment, gas characteristics, temperature range, etc. The following are some commonly used fan blade materials:
Aluminum alloy: lightweight, corrosion-resistant, suitable for small and medium-sized fans.
Carbon fiber: High strength, good rigidity, light weight, suitable for high-speed, high-temperature, and high-pressure environments.
Stainless steel: Strong corrosion resistance, suitable for humid and corrosive environments.
Cast iron: Low price, high strength, suitable for large industrial fans.
Fiberglass reinforced plastic: lightweight, corrosion-resistant, suitable for the discharge and transportation of corrosive gases such as chemicals, acids, and alkalis.
Suitable materials need to be selected based on specific usage conditions and requirements to ensure the performance and service life of the fan.
