Aluminum Alloy Wire for Heat Exchanger

Advantages

• Leak-Tight Guarantee: Superior cleanliness and consistent chemistry minimize porosity, ensuring the final product meets strict leak-testing standards.

• Thermal Management: Al-Si alloys offer excellent flow and wetting, essential for creating strong, efficient joints that optimize heat transfer.

• Automation Ready: Precision layer winding and small diameter wire ensures smooth feeding through complex robotic welding equipment, maximizing line uptime.

• Corrosion Resistance: Final joints possess the necessary corrosion resistance for long-term use in humid, demanding environments (e.g., HVAC).

FAQ

• Q: Why is ER4043 often preferred over ER5356 for heat exchangers?
• A: ER4043 (Al-Si) has a lower melting temperature and superior fluidity, which is ideal for welding thin-gauge components and cast aluminum parts, minimizing the risk of burn-through.

• Q: How do you prevent porosity in wire used for pressure-critical welds?
• A: We utilize multi-stage chemical cleaning, rigorous deoxidation during production, and immediate vacuum/moisture-proof sealing to minimize surface oxides and trapped moisture (a source of hydrogen porosity).
