Marine Applications & Product Specifications
| Application System | Core Products | Key Functions | Typical Materials |
|---|---|---|---|
| Propulsion System | Hexagonal lock nuts for propellers, hexagonal flange copper sleeves for stern shafts, hexagonal support bushes for rudder stocks | Fix propeller position, withstand high torque and impact; reduce friction in shafting and ensure flexible steering | Nickel-aluminum bronze (C63000/C63200), tin bronze (ZCuSn6-6-3) |
| Seawater Pipeline System | Hexagonal threaded connectors, hexagonal union fittings, hexagonal compression nuts for valves, hexagonal bolts for pipe supports | Connect seawater/fire pipelines, achieve sealing and detachability; adapt to different pipe diameters and resist high-pressure erosion | Silicon brass, tin bronze (ZQSn5-5-5) |
| Power and Cooling System | Hexagonal flange bolts for seawater pumps, hexagonal fastening nuts for heat exchangers, hexagonal brackets for main engine accessories | Fix pump bodies and heat exchangers, withstand high temperature and vibration; prevent seawater leakage and ensure cooling circulation | Nickel-aluminum bronze (C63000), 316L stainless steel + copper alloy combination |
| Outfitting and Deck Equipment | Hexagonal fixing bolts for deck equipment, hexagonal lock nuts for hatch covers, hexagonal connectors for lifesaving equipment | Fix deck facilities, resist salt spray and wind waves; allow quick assembly and disassembly for easy maintenance | Pure copper hexagonal nuts (for conductivity), brass hexagonal bolts (corrosion resistance) |
Precision Engineering Characteristics
Ultra-high Dimensional Accuracy
Manufactured by precision CNC turning/milling, with dimensional tolerance controlled at ±0.01-0.02 mm and thread precision up to 6H/6g, ensuring perfect fit for precision assembly of marine equipment.
Excellent Corrosion and Wear Resistance
Marine-grade copper alloys including nickel-aluminum bronze, tin bronze, and silicon brass provide superior resistance to seawater corrosion and wear.
High Structural Stability
Hexagonal structure provides anti-rotation performance and stable clamping during machining, ensuring efficient torque transmission and uniform fastening force.
Customization for Complex Conditions
Supports non-standard hexagonal sizes (M4-M60) with various surface treatments to meet requirements of commercial ships, naval vessels, and yachts.
Key Selection & Application Guidelines
- Prioritize materials with classification society certifications (CCS, ABS, etc.) to meet marine safety standards
- Use nickel-aluminum bronze for key propulsion components to balance strength and corrosion resistance
- Choose tin bronze or silicon brass for pipeline seals to avoid galvanic corrosion
- Use professional torque tools for installation to prevent thread damage or loosening
Advanced equipment and technology from Japan and Germany (CNC 5-axis and 6-axis machines) with maximum processing outer diameter of 60mm and minimum control tolerance of 0.001mm.
