Marine multi-blade boat propeller is kind of a fixed-pitch boat propeller with more blades 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 multi-blade 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. Boat propeller blades can be customized.
And Marine society class certificate for this boat propeller,ABS, BV, CCS, DNV(GL),NK,RINA are available.
The structure of the constant-speed boat propeller is relatively simple, lightweight, low in cost, and easy to maintain.
Due to its simple structure and low cost, the constant-distance boat propeller is widely used in small-power, light and ultra-light aircraft.
Marine multi-blade boat propeller 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
