All Sensenich aluminum propellers are manufactured from 2025 forged aluminum. The propellers are CNC machined and hand-finished to very tight tolerances. Each propeller then goes through a rigid 56 point inspection to assure you of the highest quality, most problem free propeller available. All aluminum propellers are vibration tested before being approved for use on any engine.
