The fixed-pitch marine boat propeller is a type of propeller in which the blades are permanently fixed to the hub during casting, and the blade installation angle (or pitch) remains constant.
We are able to design and manufacture marine boat propeller. The material of this boat propeller can be Nickle aluminum bronze, Manganese bronze.
The diameter of this marine boat propeller can be from less than 1M to more than 8M.
And Marine society class certificate for this boat propeller,ABS, BV, CCS, DNV(GL),NK,RINA are available.
Simple structure: The structure of the constant-speed boat propeller is relatively simple, lightweight, low in cost, and easy to maintain.
Widely applied: Due to its simple structure and low cost, the constant-distance boat propeller is widely used in small-power, light and ultra-light aircraft.
Performance limitations: The main drawback of fixed-pitch boat propellers is that they cannot maintain optimal performance under various operating conditions. Once the boat propeller is installed on the engine crankshaft, the pilot cannot change the blade angle. Therefore, the maximum efficiency of the boat propeller can only be achieved at a specific forward ratio, and the efficiency at other speeds will be lower than the maximum value.
Simple structure, light weight, low cost, and easy maintenance.
Manufacturing materials and processes of marine fixed-pitch propellers:
Marine fixed-pitch propellers can be produced for ships with a length of less than 8 meters and a finished weight of about 35 tons. Common materials include first-grade manganese bronze (Cu1), second-grade nickel-manganese bronze (Cu2), third-grade nickel-aluminum bronze (Cu3), and fourth-grade manganese-aluminum bronze (Cu4).
Cu1(Manganese Bronze) and Cu3(Nickel Aluminum Bronze) are two commonly used copper alloy materials in the manufacture of marine propeller.
Cu1：Suitable for inland rivers, low cost , durable enough for freshwater environment
Cu3：Stronger strength and corrosion resistance, high corrosion resistance to seawater immersion
