Product Overview
We specialize in manufacturing high-performance marine propellers, including Fixed Pitch Propellers (FPP) and Controllable Pitch Propellers (CPP), with 3 to 6 blades available. Crafted from premium copper alloys (Cu1/Cu2/Cu3/Cu4) and featuring a skewed blade design, our propellers excel in efficiency, corrosion resistance, and low noise/vibration performance. Backed by global certifications and flexible OEM/ODM services, they are tailored for various ships, from container vessels to tankers.
Core Parameters & Specifications
1. Design & Configuration
- Type: FPP (Fixed Pitch Propeller) and CPP (Controllable Pitch Propeller)
- Blades: 3/4/5/6 blades (customizable based on vessel type and performance needs)
- Skewed Blade Design: Reduces cavitation, noise, and hull vibrations by optimizing water flow dynamics, enhancing hydrodynamic efficiency
- Diameter Range: 0.5m - 12m (covers small boats to large bulk carriers)
- Weight: From hundreds of kilograms to 140 tonnes (supports heavy-duty marine applications)
2. Material & Corrosion Resistance
- Alloy Options:
- Cu1 (Manganese Bronze): ZCUZn40Mn3Fe1, ideal for general marine use
- Cu2 (Mn-Fe Bronze): ZCUZn21Al5Fe2Mn2, high strength for medium-duty vessels
- Cu3 (Ni-Al Bronze): ZCUA9Fe4Ni4Mn2 / ZCUAl8Mn12Fe3Ni2, excellent corrosion resistance in seawater, suitable for heavy-duty ships
- Cu4 (Mn-Al Bronze): ZCUAl8Mn14Fe3Ni2, wear-resistant for high-speed vessels
- Corrosion Resistance: All copper alloys meet international shipbuilding standards, with Cu3/Cu4 showing superior resistance to seawater erosion, ensuring long-term durability in harsh marine environments
3. Performance Advantages
- Efficiency: Optimized blade geometry (pitch ratio, area ratio) and skewed design minimize energy loss, maximizing propulsion efficiency (tested to reduce fuel consumption by 8-15% compared to standard propellers)
- Cavitation Control: Precision-engineered to reduce cavitation (bubbles in water flow), which lowers noise and prevents blade erosion
- Vibration Reduction: Skewed blades reduce pressure pulses on the hull, lowering vibration levels by 10-20% (critical for passenger comfort and equipment longevity)
- Strength: Meets strict strength requirements for heavy-duty operations, withstand high torque and load from large marine engines
4. Certifications
