What Are the Benefits of Composite Propellers? - Hartzell. Structural composite aircraft propellers have grown popular in aviation, for many reasons. An increasing number of aircraft manufacturers select composite propellers as standard equipment on their airplanes, and more aircraft owners are choosing to make the switch to carbon fiber props after an overhaul or replacement.【Get Price】

What are the Pros and Cons of Aluminum Propellers? There are also downsides to using aluminum propellers. In aircraft, the aluminum propeller is prone to becoming lightly pitted by sand and debris. The soft alloy is also prone to corrosion. This all means that extra maintenance will be required as compared to using a wooden or composite propeller. Expense is typically a great concern with most.【Get Price】
