Aluminum windows and doors hardware exposed to the humid air long-time, to accelerate the corrosion happened. In the hot and humid summer, with the temperature rise will accelerate the corrosion of aluminum windows and doors hardware, while large temperature difference between day and night. The air is filled with PM2.5, sulfide, corrosive media. Acid and alkali substances will be adsorbed on the aluminum windows and doors hardware caused acid corrosion.
