Import Customized Marine Propeller — Buy in Bulk from Supplier in China

The Customized Marine Propeller from Kingloo Marine Machinery Co., Ltd. is cast in bronze alloys, specifically CU1 and CU3 grades, with diameters ranging from 600 mm to 6000 mm. Each propeller is designed to match vessel engine power, gear ratio, and hull hydrodynamics, ensuring optimal thrust efficiency and reduced vibration. The supplier specializes in fixed-pitch and controllable-pitch propellers for commercial and high-speed vessels.

CU1 bronze contains approximately 88% copper, 8% tin, and 4% zinc, offering high strength and corrosion resistance in seawater. CU3 adds nickel for improved fatigue resistance, suitable for high-speed applications. Casting is performed using sand or permanent mold techniques, followed by precision machining to meet NACA or Bp series blade profiles. Surface finish is typically polished to Ra 1.6 µm for hydrodynamic efficiency.

Buyers include shipyards, vessel owners, and propulsion system integrators operating in coastal and international waters. The supplier exports to markets including Singapore, the U.S., Germany, and Taiwan. Propellers are supplied with hub assemblies and keyways machined to ISO 484-1 standards. Lead time varies with size and complexity, typically 8 to 16 weeks. Trade terms include FOB Guangzhou port or CNF destination, with documentation provided per client requirements.
