Cooling fan blades are usually made of lightweight, heat-resistant materials such as plastic and aluminum alloy cellulose sheets. These materials conduct heat efficiently and can be rotated at high speeds during operation without damage. In addition, they have good insulating properties that prevent electrical short circuits. Fan blades made of plastic are lightweight, abrasion-resistant, and corrosion-resistant, but are less resistant to high temperatures and are usually used for household appliances or other small devices. Metal fan blades are stronger and more durable, can withstand higher temperatures, and are often used in industrial environments for large equipment or chassis fans. Fan blades made of cellulose board are environmentally friendly, lightweight, and anti-static, and are commonly used for fans in server rooms or data centers.
