Propeller blade straightening involves correcting bent or misaligned blades to restore optimal performance. Ship propeller repair includes fixing damages like cracks, erosion, or deformities to ensure smooth operation. Both processes are crucial for maintaining fuel efficiency and vessel safety.

Size: Typically ranges from 0.5 meters to 10 meters in diameter, depending on vessel type.

Grade: Marine-grade alloys (e.g., NiAlBronze, Manganese Bronze, Stainless Steel).

Viscosity: Not applicable (solid metal components).

Buoyancy: Neutral or negative (depends on material density and design).

Material: High-strength corrosion-resistant alloys (e.g., CuNi, NiAlBronze, Stainless Steel 316).

Repair Methods: Heat straightening, cold straightening, welding, machining, and balancing.

Surface Finish: Smooth polished to reduce hydrodynamic drag.

Weight: Varies by size and material (e.g., 50 kg to 5,000 kg).

Operating Temperature: -20°C to 80°C (marine environment).

Corrosion Resistance: High (due to marine-grade coatings or alloy properties).
