What is the material used of propeller?

Propellers are commonly made from a variety of materials, including aluminum, stainless steel, and composite materials. Aluminum is lightweight and cost-effective, while stainless steel offers durability and resistance to corrosion. Composite materials, such as fiberglass or carbon fiber, are also used for their strength-to-weight ratio and ability to withstand harsh conditions. The choice of material often depends on the specific application and performance requirements of the propeller.
