What are the materials uses in propeller shaft?

Propeller shafts are commonly made from materials such as steel, aluminum, and composite materials. Steel is often used for its strength and durability, while aluminum is favored for its lightweight properties, which can improve fuel efficiency. Composite materials, like carbon fiber, are increasingly utilized for their high strength-to-weight ratio and resistance to corrosion. The choice of material depends on factors like the application, required strength, weight considerations, and cost.
