Core Advantages
. Marine-Grade Performance: Resists seawater corrosion and biofouling.
2. High Thermal Efficiency: Ideal for condenser and heat exchanger systems.
3. Versatile Fabrication: Compatible with hot forging, extrusion, and welding.
4. Cost Efficiency: Optimized for large-scale industrial applications.
Product Applications
Marine Engineering: Ship hulls, propeller shafts, and seawater valves.
Heat Exchangers: Condenser tubes, radiator cores, and boiler components.
Construction: Architectural cladding, roofing, and decorative trim.
Industrial: Fasteners, bolts, and heavy-duty stamped parts.
Processing Considerations
Hot Working: Forge or extrude at 650–800°C; avoid overheating to prevent zinc loss.
Annealing: 500–600°C for stress relief after cold working.
Welding: Use TIG or MIG welding with inert gas shielding; pre-clean surfaces.
Surface Protection: Apply anti-corrosion coatings for prolonged marine exposure.
Key Application Scenarios
Offshore oil rig components exposed to seawater.
Power plant condenser and heat recovery systems.
Coastal architectural structures requiring corrosion resistance.
Heavy machinery parts in chemical processing plants.
