Carbon Steel
Frequently used in general centrifugal fans, carbon steel refers to an iron-carbon alloy with a carbon content of less than 2.11%. This material is easy to manufacture and cost-effective, making it suitable for most applications involving substances at normal temperatures. It is especially effective for dust-free and non-corrosive environments.
Fiberglass-Reinforced Plastic (FRP)
FRP, commonly referred to as fiberglass, is a widely used material in centrifugal fans. It offers excellent resistance to various acids and alkali salts, making it ideal for handling diverse gases in the chemical manufacturing industry.
Stainless Steel
Stainless steel is another common and essential material for centrifugal fans. It encompasses over 100 specific grades, including martensitic, austenitic, ferritic, and duplex stainless steels, offering versatility for different industrial needs.
Plastic Materials
Certain centrifugal fans use plastic as a primary material, typically polypropylene (PP). However, due to its lower tensile strength compared to fiberglass, its application scope is limited. Despite this, plastic fans find specialized use due to their unique properties, such as lightweight construction.
Specialty Materials and Composites
Centrifugal fans also utilize materials like aluminum alloys, plastic-lined components, or fiberglass-lined structures. While less common, these materials play critical roles in niche applications where their unique properties are indispensable.
