Core Application Fields
Building Hardware: Door and window fittings, locks, plumbing fittings.
Electronics and Electrical Appliances: Heat exchangers, conductive terminals, switch contacts.
Mechanical Manufacturing: Screws, rivets, washers, stamped parts.
Decorative Materials: Metal mesh, decorative strips, crafts.
Industrial Equipment: Condenser tubes, heat exchangers (must be protected from seawater corrosion).
Processing Considerations
Annealing Process: Requires annealing at 550-650℃ after cold working to eliminate internal stress and prevent cracking.
Welding Requirements: Preferably use argon arc welding to reduce the zinc evaporation and pore defects.
Corrosion Protection: Avoid direct exposure to seawater or ammonia environments; it is recommended to add a coating or plating.
FAQ
Q: What is the difference between H62 brass and H59 brass?
A: H62 has a higher copper content (60.5%-63.5% vs. H59's 57%-60%), offering better plasticity, making it suitable for complex processing. H59 has slightly lower strength but is more cost-effective.
Q: Is H62 material suitable for seawater environments?
A: It is not recommended for direct use, as the corrosion rate is relatively high (around 0.1-0.15 mm/a). It is recommended to add a coating or use a corrosion-resistant alloy (such as HSn62-1 tin brass).
