The main materials for marine propellers and the differences Article By Robin Zhang The propeller is used as a powerful force-receiving component for propulsion. The internal strength requirements are also high, and there should be no tracheotomy or air bubbles. Therefore, the blades of large propellers cannot generally be formed by forging. At present, high precision casting is the main meth...
