Product Description
Propeller diameter: 850mm,
EAR: 0.83
Blades: 4
Turning direction: Left
Weight: 60kg
Material: Nickel Aluminum Bronze (Cu3)
Inspection: 1. material test, 2. pitch, thickness, width, 3. weight, 4. static balance, 5. PT test, 6. hole, etc.
We design and supply propellers for container ships, cargo ships, tankers, tug boats, trawlers, and fishing boats.
The materials:
Cu1, which contains zinc, bronze, iron, and manganese (but nickel and aluminum are not included). Cu3 contains nickel, aluminum, bronze, iron, stainless steel, and manganese.
Dimensions: Based on your requirements
Our capabilities: Can design and manufacture propellers whose diameter can be from less than 1 m to more than 8 m.
All the propellers are approved by ABS, BV, CCS, DNV, GL, KR, LR, NK, etc., and have obtained the authentication certificate of quality system ISO 9001:2000.
Marine boat propeller material selection:
Cu3 (Nickel Aluminum Bronze): Seawater Resistance + High Strength, the "Reliability Standard" for Key Marine Components
Natural Barrier Against Marine Corrosion: With a corrosion rate in seawater Cu1's 1/10-1/5 and 304 stainless steel's 1/3 (close to 316L), its aluminum-formed oxide film self-repairs, eliminating regular painting maintenance and significantly reducing ocean vessel operational costs.
High Load-Bearing Capacity: Tensile strength (600-850MPa) ranks highest among the three, withstands "cavitation impact" and "torque loads" during high-speed propeller rotation (e.g., large marine propellers with 5-8m diameter and 10-20t weight require Cu3's strength support).
Lightweight Potential: 5%-12% lower density than Cu1 allows weight reduction for components at equivalent strength (e.g., 5%-10% lighter propellers), indirectly reducing vessel fuel consumption and aligning with "green ship" trends.
