IX. Часті запитання (Q&А)

Q1. Why does 3003 aluminum foil have better corrosion resistance than pure aluminum foil?

3003 aluminum foil belongs to the Al–Mn alloy series. The manganese content is controlled at 1.0–1.5%, which forms a more stable alloy microstructure on the surface of the aluminum foil, effectively blocking the intrusion of oxygen and moisture. Compared with 1235 pure aluminum foil, its corrosion resistance is improved by more than 40%. В додаток, corrosion resistance can be further enhanced through passivation treatment, and salt spray resistance time can reach more than 200 години, making it suitable for humid and outdoor environments.
