◎Selection principle of fan impeller material

The material selection of the fan impeller should be based on the use of the impeller environment, considering the strength of the impeller, hardness, corrosion resistance, fatigue resistance, heat resistance, explosion-proof and other factors.

◎Fan impeller commonly used materials and characteristics

1. Aluminum alloy: Aluminum alloy impeller has the characteristics of light weight, high strength, corrosion resistance, not easy to deformation, etc., suitable for occasions with small air volume.

2. Cast iron: Cast iron impeller has the characteristics of high strength, high hardness, good wear resistance, good heat resistance, etc., suitable for the occasion of large air volume.

3. Carbon steel: carbon steel impeller has the characteristics of high strength, high hardness and good wear resistance, but it is easy to rust and corrosion, and needs regular maintenance and protection.

4. Stainless steel: Stainless steel impeller with high strength, high hardness, corrosion resistance, not easy to rust, easy to clean and other characteristics, is currently one of the most widely used fan impeller materials.

5. Polyurethane material: polyurethane material has the characteristics of good wear resistance, good corrosion resistance, light density, etc., suitable for fans in chemical, electronics, pharmaceutical and other fields.

◎Fan impeller material selection precautions

1. The suitable material should be selected according to the use environment of the fan, the force of the impeller and other factors.

2. Different materials of impeller applied to different occasions, can not be mixed.

3. The thickness of the impeller can be appropriately increased to improve the fatigue resistance of the impeller.

4. Maintain the impeller regularly to extend the service life of the impeller.
