Corrosion resistance and service life
- Aluminum alloy: Compact oxide film (ALO) is naturally formed on the surface, which is resistant to atmospheric corrosion, but easy to be corroded in acidic or alkaline environment.
- 2. galvanized sheet: the zinc layer can delay the rusting of the substrate through electrochemical protection, and its service life can reach 20-50 years (ISO 1461 standard) in a humid environment, but the protection of the zinc layer decreases after wear.
